Planet - Flock Imaging Constellation
On Nov. 26, 2013, Planet Labs, a private start-up company of San Francisco, CA, announced that it successfully launched its most recent nanosatellites, Dove 3 and Dove 4, into orbit on a Dnepr vehicle (launch on Nov. 21, 2013 from the Yasny Cosmodrome, Russia), completing a series of four prototype nanosatellites in 2013. Those proved successful, enabling the company to quickly follow up with the production of a 28-member network. The launch of Planet Labs’ "Flock 1" fleet of 28 nanosatellites in December/January, which will be the largest constellation of Earth-imaging satellites ever launched. 1) 2)
The latest additions to the Planet Labs fleet offer improvements in the capability provided by the firm’s first nanosatellites launched in April, Dove 1 and Dove 2, which also were 3U CubeSats. Dove 3 and Dove 4 will demonstrate the firm’s latest technology, including upgraded communications, attitude control and observation technology.
Background: Planet Labs was founded in 2010 by Chris Boshuizen, Will Marshall and Robbie Schingler, three NASA alumni interested in altering the space industry. Their “Dove” nanosatellites are meant to be low-cost and rapidly deployable, and capable of taking pictures of Earth that provide a spatial resolution of 3-5 m. — On March 17, 2014, Planet Labs announced that it has confirmed launches for more than 100 satellites over the next 12 months. This full constellation of nanosatellites will allow Planet Labs to image the entire Earth every day. 3)
The Flock 1 constellation nanosatellites (all 3U CubeSats) were designed and built by Planet Labs Inc. They feature mostly COTS (Commercial-off-the-Shelf) components, including their imagers. Each nanosatellite has a mass of ~5 kg and a size of 10 cm x 10 cm x 34 cm.

It can be expected, that the Flock 1 nanosatellite design corresponds closely to the design of the prototype Dove series, which demonstrated that the company’s engineers can accurately position the orbiters and capture a continuous stream of imagery with a resolution of 3-5 m.
ADCS (Attitude Determination and Control Subsystem): The attitude is sensed by magnetometers, gyros and photodiodes. The attitude is being controlled by magnetorquers and reaction wheels. The B-dot controller makes use of the B field to reduce the angular rate of the satellite. In this control mode, Dove-1 therefore behaves as a permanent magnet, remaining locked and axis-aligned to the Earth’s magnetic field. - Dove-1 will be nadir pointing twice per orbit. The alignment of the magnetic field is known to about 1º at any point.
EPS (Electrical Power Subsystem): The bus provides central power control through a power supply to the camera, the flight computer and the magnetorquers. The power supply regulates the voltages and ensures a stable power supply to each component. Power storage is provided by 8 Lithium-ion cells, providing 20 Ah of charge at full capacity. The batteries will be recharged by body-mounted TASCs (Triangular Advanced Solar Cells).
C&DH (Command & Data Handling) subsystem: C&DH is controlled by the single board computer. Additionally there will be a discrete watchdog board that will be able to reboot the flight computer in the event of errors.
RF communications: The communication subsystem consists of a VHF radio beacon for transmitting telemetry and an S-band frequency hopping spread spectrum modem for two-way communication and as the primary radio for data downloading. After powering up, the first mission event is to transmit telemetry data over the VHF beacon. The beacon will transmit health packets (including temp/power supply/current/RSSI/solar vector/acceleration) at 1200 baud AFSK approximately every 30 seconds (AX.25 protocol, 145.825 MHz). The beacon can transmit at up to 1 W and will use a quarter wave monopole antenna cut from tape measure.
The S-band radio will operate in the 2.4 GHz half-duplex ISM (Industrial, Scientific and Medical) band at a wireless link rate of 115 kbit/s using a patch antenna.
In Nov. 2013, Planet Labs' Flock 1 nanosatellites were delivered to NASA's Wallops Flight Facility in Virginia for launch on board an Antares rocket in December 2013. These satellites were built in production at the Planet Labs headquarter offices in San Francisco. Planet Labs is on track to launch 32 satellites on four different launches in 2013. 5)
Radio Development History(update to RF communications): 6)
In order to meet Mission 1 data volume objectives, Planet built a custom high-speed X-band radio using COTS components that is tightly integrated with the rest of the CubeSat bus. Several radio architecture decisions were made in order to meet the size, weight, and power (SWaP) constraints of the CubeSat platform while also improving the overall system efficiency. For example, the final stage RF power amplifier was integrated adjacent to the antenna to improve the total system power efficiency. This allowed the use of antenna solutions with 10-12 dBi gain, but still achieve data rates comparable to much larger class satellites that typically have very high gain antennas.
The custom development solution also allowed for rapid prototyping and repeated iterations that led to continuous improvements to the radio subsystem. Planet's first satellite launch hosted the sixth iteration (Build 6) of the spacecraft that transmitted 2 W of RF power through a 3 dBi gain patch antenna. A 6.1 m dish at the Chilbolton Observatory in the UK served as the ground station antenna. On April 25, 2013, Planet achieved its first successful X-band downlink at 4 Mbit/s data rate, which set a new data rate record for CubeSat class satellites.
The success of the early launches and tech demos proved that Planet could meet its Mission 1 goals by following the \agile aerospace" philosophy of rapid prototyping, repeated iterations, and continuous improvements. Less than three years after the first launch, the thirteenth iteration (Build 13) of the satellites was launched on the Indian Polar Satellite Launch Vehicle (PSLV) in June 2016. This constellation code named Flock 2P or F2P included twelve \Build 13" satellites (launch in June 2016). Further improvements were made to this build and Flock 3P or F3P consisting of 88 satellites was launched in February 2017. With the F3P launch, Planet set a record for the most number of operational satellites (100 Build 13 satellites and several B10, and B12 satellites). Planet has demonstrated 220 Mbit/s peak data rates with the Flock 3P constellation and average data rates of approximately 160 Mbit/s. Cumulatively, these satellites generate several TB of imagery data daily that is downlinked to eight geographically diverse ground station sites. The active imaging satellites and the ground stations are shown in Figure 61.
Improvements to the spacecraft HSD (High-Speed Data) system have followed Planet's iterative design approach. Higher gain antennas have been added and improved, RF circuit impairments have been addressed, amplifier settings have been optimized, and the radio firmware and software has undergone constant development. Table 1 provides a summary of key HSD development milestones.
The HSD radio operates at X-band with a center frequency of 8150 MHz and 70 Mbaud symbol rate. This frequency is within the 8025-8400 MHz (X-band) range where EESS (Earth Exploration Satellite Service) has a primary spectrum allocation.

Launch: The Cygnus CRS-1 logistics flight of Orbital Sciences to the ISS was launched on Jan. 09, 2014 on an Antares-120 Vehicle of OSC from MARS (Mid-Atlantic Regional Spaceport), Wallops Island, VA. 8)
Cygnus CRS-1 (Commercial Resupply Services) Orb-1 logistics flight of Orbital Sciences is the second Cygnus flight to the ISS (International Space Station) and the third launch of the company's Antares launch vehicle from MARS (Mid-Atlantic Regional Spaceport), Wallops Island, VA. The flight is the first of 8 under the CRS (Commercial Resupply Services) contract to NASA. The mission is scheduled to launch on December 18, 2013. Cygnus is expected to deliver 550 kg of cargo to ISS and dispose of about 1,000 kg through destructive reentry.
Orbit: Near-circular orbit of the ISS, altitude between 370-430 km, inclination = 51.6º. — Planet refers to a group of Doves deployed simultaneously into a single orbit as a flock.
Secondary payloads: commercial payloads of Orbital Sciences.
Part of the Cygnus payload consists of 33 CubeSats which will be deployed in early 2014 with the NanoRacks Smallsat Deployment Program using the J-SSOD (JEM-Small Satellite Orbital Deployer), located in the airlock of the JEM/Kibo module of JAXA.
The CubeSats are:
• 28 Flock 1 3U CubeSats, the first generation of an Earth observation constellation of Planet Labs. They will be placed into 400 km circular orbits (inclination of ~52º), providing imagery with a resolution of 3-5 m. 9)
• LituanicaSAT-1, a CubeSat which will carry a VGA camera, a GPS receiver and a voice transponder. The satellite has been developed at the Vilnius University (Lithuania) and has been named after the aircraft named Lituanica that flew across the Atlantic Ocean 80 years ago.
• LitSat, a 1U CubeSat developed by the Lithuanian Space Federation. The satellite will carry an onboard VGA camera and a GPS receiver.
• UAPSAT, a 1U CubeSat developed by UAP (Universidad Alas Peruanas), Lima, Peru, as a student educational project. Once in orbit the satellite can be accessed by radio amateurs; UAPSAT will test the behavior of electronic design communication, orientation and stabilization and verify the implementation of the technology and methodology used in the manufacture of the satellite.
• SkyCube, a 1U CubeSat developed by the Southern Stars Group LLC (San Francisco, CA) and funded by thousands of sponsors and mobile app users around the world (crowd funding). Its objective is to facilitate global grassroots public outreach and educational effort whose purpose is to make space exploration accessible as never before by allowing participants to send simple broadcasts - "tweets from space". The satellite is also fitted with a camera for on-demand pictures of Earth. At the end of the 90 days mission, SkyCube will inflate an onboard balloon that will make it visible to the unaided eyes and assist in de-orbiting the satellite cleanly through atmospheric drag. 10)
• Ardusat-2, developed by Nanosatisfi LLC, which is similar to the Ardusats that were sent to ISS earlier this year.
On January 12, 2014, the Cygnus CRS-1 spacecraft arrived at the ISS where Expedition 38 astronauts grappled the spacecraft and berthed it in a flawless operation (Figure 4).
Launch: On Oct. 31, 2017 (21.37 UTC), six SkySat minisatellites of Terra Bella (a Planet Labs company) and 4 Dove (Flock-3m) nanosatellites of Planet Labs were launched on a Minotaur-C vehicle of Orbital ATK from VAFB, CA (SLC-576E). The Minotaur-C is an upgraded, renamed version of the Orbital Sciences Taurus rocket. Approximately 12 minutes into flight, the ten commercial Planet spacecraft deployed into their targeted sun synchronous orbit of 500 km altitude. 11) 12)
Orbit: Sun-synchronous orbit, altitude of ~500 km, inclination of ~97º.

Status & development of the Planet Labs Flock Nanosatellite Constellation — and the fleet acquisitions
• November 17, 2021: Emergency managers require up-to-date information throughout the lifecycle of an incident on the conditions of impacted communities in order to make decisions about where and how to respond. Planet’s high-cadence and high-resolution satellite monitoring capabilities and image archive provide ongoing regional coverage, enabling disaster risk mitigation, rapid response, and informed recovery. 14)
- Our data is now being used through a collaboration with New Light Technologies Inc. (NLT) to provide the Federal Emergency Management Agency (FEMA) imagery to support enhanced situational awareness for effective disaster response.
Figure 7: These two false color PlanetScope images show the direct aftermath of Hurricane Michael on the coastal community of Mexico Beach, Florida. In the second image, taken on October 11, 2018, the day after the hurricane made landfall it is possible to see large areas of damage and inland flooding throughout the community (image credit: Planet)
- The NLT team utilized PlanetScope to evaluate predictive deep learning models of tornado damage, examine the impacts of the New Waverly floods in Texas, and conduct visual assessments of infrastructure damage caused by winter storms. Our SkySat satellites have also been employed by FEMA on a tasking basis to gain enhanced high-resolution insights to complement the near-daily datasets. This advanced visual coverage supports the organization’s ability to keep impacted communities safe and informed.
Figure 8: This true color SkySat image, taken on October 17, 2018, shows the extent of the destruction (image credit: Planet)
- Planet’s data is particularly useful for disaster management as evaluators can gain a before-and-after look at key regions within 24 hours of catastrophic events and effectively target relief efforts. Through our archive imagery dating back to 2009, this time series data also supports FEMA’s ability to mitigate risk and plan for climate resilience and adaptation, revealing regional patterns and global change.
Figure 9: Tornado path mapping. These two true color PlanetScope images show the damage caused by the longest tornado to touch down during a storm on the night of March 25, 2020 in central Alabama. This tornado, an EF3, left a path of damage that was 80 miles long (image credit: Planet)
- Our data has supported a number of other disaster response initiatives ranging from preventative research to rapid relief. Through Planet’s Education and Research Program, scientists utilized PlanetScope data to create predictive tools monitoring earthquakes and landslides in the Himalayas, and by pulling our data just hours after the Chamoli landslide, researchers were able to understand how the event occurred. In 2018, the World Food Program and the Republic of the Congo leveraged Planet’s data to create the Cloud to Street flood mapping and response organization. In collaboration with NASA Harvest, our data also supported rapid food and agriculture response in Togo as COVID-19 disrupted food security.
- Serving FEMA aligns with Planet’s continued growth and long-term mission to support global communities by revealing near-daily global change. Earlier this year, Planet entered into a definitive merger agreement with dMY Technology Group, Inc. IV (NYSE:DMYQ), a special purpose acquisition company, to become a publicly-traded company. As we join the public market, Planet will become a public benefit corporation (PBC), in which our mission will be encoded into our corporate DNA, obligating Planet’s directors to stay true to our mission as part of their fiduciary duty to our stockholders. Planet’s public benefit purpose is: “To accelerate humanity to a more sustainable, secure and prosperous world by illuminating environmental and social change.”
• November 10, 2021: We are excited to announce that Planet has entered into an agreement to acquire VanderSat, a leading provider of advanced earth data and analytics. Vandersat’s innovative products help customers better measure and understand water management and crop health in major markets. Planet intends to leverage VanderSat’s technologies and products in further pursuit of bringing to market next-generation solutions that combine the best of commercial and public satellite data to provide clear and actionable information to help industries, non-profits, and governments around the world. 15)
VanderSat has world-class expertise in providing insights to customers by drawing from NASA, ESA and JAXA satellite data, and has built a suite of novel products that report on key conditions on the Earth’s surface, like soil moisture, land surface temperature, vegetation optical depth, and biomass. VanderSat’s unique algorithms deliver daily, global data products with great accuracy, unhindered by changing cloud-cover and atmospheric conditions.
“VanderSat is a mission-driven company with the goal to serve one billion hectares of land in 2024. By joining Planet, our mission and impact will be dramatically accelerated and together, we aim to reach that goal in 2022,” said Dr. Thijs van Leeuwen, CEO of VanderSat.
“We’re thrilled to be welcoming the VanderSat team to Planet. We expect VanderSat’s analytics and industry expertise will help Planet provide solutions ‘up the stack’ to bridge the gap from complex remote-sensing science to products that offer improved data to the ecosystem and our customers. And when one combines their new data with Planet’s, the value is far greater than the sum of its parts,” said Will Marshall, CEO and Co-Founder of Planet. “We believe VanderSat’s products will add value in Planet’s core verticals of agriculture, and civil government, and will help us open up to others such as insurance and banking, to help grow our business.”
At Planet, one of our goals is to bridge the gap between real-world problems and the complexity of remote-sensing science. VanderSat is another step towards that goal with their advanced analytics. We believe their products will accelerate and expand our position in one of our most important verticals – agriculture – and help mature our offerings for others such as insurance, civil government, and finance. For example, easier-to-consume data can enable modeling to help financial institutions and insurers quantify climate impacts on water availability and crop production.
Adding VanderSat’s unique, all-weather data products to Planet’s high-cadence and high-resolution global monitoring will bring even greater value to users in agriculture, civil government and insurance by providing them with richer insights and more precise measurements. Plus, Planet’s unique platform and integrations will make these products more accessible than ever before.
The VanderSat team is based in Haarlem, Netherlands and will further increase Planet’s commitment to the European ecosystem. The entire team, including their founder Dr. Richard de Jeu and CEO Dr. van Leeuwen, will be joining Planet.
Under the agreement, Planet is set to acquire VanderSat for approximately $28 million, which consists of $18 million in shares of Class A common stock of Planet Labs PBC, valued at a per share price equal to the closing price of Class A common stock of Planet Labs PBC on the NYSE on the last trading day prior to the consummation of the acquisition of VanderSat, and approximately $10 million in cash.
The transaction is expected to close in Q4 2021 and is subject to customary closing conditions, as well as the closing of Planet’s business combination with dMY Technology Group, Inc. IV (“dMY IV”). This will be Planet’s fourth acquisition (BlackBridge ‘15, Terra Bella ‘17, and Boundless ‘19).
We are thrilled to welcome VanderSat to the Planet family!
• October 12, 2021: This morning at our Explore 2021 user conference, we announced two major new products: Pelican, a next-generation fleet of satellites for very high resolution imagery that will begin launching next year and be operational in 2023, and Fusion with SAR, a cutting-edge data enhancement to our existing Fusion Monitoring product. 16)
- When fully operational, the Pelican constellation replenishes and upgrades Planet’s existing high resolution SkySat fleet with better resolution, more frequent image revisit times, and reduced reaction time and latency. The Fusion line will now include SAR (Synthetic Aperture Radar) data, enabling customers to see through clouds with a data stream of continuous landscape monitoring.
Figure 10: Planet unveiled “very high resolution” Pelican Earth-imaging satellites, which the company plans to design, build and manufacture in-house (image credit: Planet Labs Inc.)
- With increased response times, Pelican customers will be able to task and receive images with significantly reduced latency. The constellation will offer enhanced image resolution, enabling customers to see fine details like road markings. When fully operational, the Pelican fleet will exceed SkySat’s market-leading global intraday revisit frequency of up to 10 times. When paired with Planet’s full suite of daily, global monitoring data and analytics solutions, Pelican will enable powerful new insights that drive unparalleled awareness and decision making for our users working in government, sustainability, finance, insurance, and more. The Pelican constellation was designed in-house and will be built at our headquarters in San Francisco.
- “Pelican significantly advances Planet’s product suite with the highest temporal resolution and revisit times that we have ever offered, while dramatically reducing the time between tasking and receipt of an image. In a world that is increasingly fast-changing and unpredictable, this kind of detailed information on demand will be a game changer for our customers who every day need to make quick, consequential decisions,” said Planet’s Senior Vice President of Space Systems James Mason.
- Our agile and modular approach towards designing and building spacecraft and software enables us to quickly innovate our products, providing timely, detailed, and unique datasets to customers every year. In this vein, the Pelican satellite architecture leverages that of the Carbon Mapper constellation, which was announced in April 2021. This modularity and multi-mission flexibility is a defining characteristic of our agile aerospace methodology and enables the company to pursue two critical and ambitious missions quickly and affordably.
Fusion with SAR
- Last year at Explore 2020, we announced Fusion Monitoring, a unique solution that combines Planet’s daily, global PlanetScope monitoring data with additional datasets to deliver a consistent stream of information about a customer’s area of interest. This year, we will now merge SAR data from Sentinel 1 into the Fusion line, providing improved sensing to customers in the agricultural sector. This additional data stream will help to boost the reliability of agronomic models that consume Fusion data, especially in very cloudy regions. SAR data has the advantage of imaging through clouds and weather that obscure optical data. By incorporating SAR data into the Fusion product, Planet can offer superior continuous monitoring of crop health and capture key events like harvesting or the effects of storm damage.
Figure 11: SAR enabling advanced imaging of areas previously obscured by cloud cover over Eksel, Belgium in 2021, image credit: Planet Labs Inc.)
- All of Planet’s data is analytics ready. This is the foundation of our Fusion product line and core to our ability to combine Planet data with that of other sensors,” said Planet President Kevin Weil. “By incorporating SAR into our daily Fusion monitoring product we ensure direct measurements regardless of cloud cover, providing more insights to our customers to reliably power their decisions.”
- Earlier this year, we entered into a definitive merger agreement with dMY Technology Group, Inc. IV (NYSE:DMYQ), a special purpose acquisition company, to become a publicly-traded company.
- Planet executives are not revealing the size of the planned Pelican constellation, saying it will largely be determined by market demand. 17)
- “If and when the market is there, we can put more satellites in space and we have the ground stations and the ground-processing capability in order to handle more and more data,” Schingler said.
- In addition to processing its own imagery, Planet merges imagery from its own flock of 180 Doves with imagery from the European Copernicus Sentinel 2, NASA’s Moderate Resolution Imaging Spectroradiometer and the U.S. Geological Survey-NASA Landsat to create Planet Fusion Monitoring, a cloud-free data source.
- Planet Fusion Monitoring will now include Sentinel 1 SAR data, which can be acquired at night and through clouds.
- “By incorporating SAR into our daily Fusion monitoring product, we ensure direct measurements regardless of cloud cover, providing more insights to our customers to reliably power their decisions,” Planet President Kevin Weil said in a statement.
- Over the last two years, Planet engineers have designed two new sensors. One is the hyperspectral sensor for Carbon Mapper satellites to pinpoint, quantify and track sources of methane and carbon dioxide. Pelican’s sensor is the second.
- Planet is preparing to go public through a merger with dMY Technology Group, Inc. IV, a special-purpose acquisition company.
- Going public will give Planet access to the funds the company needs to “build up the team and build out the Earth data platform,” Schingler said. “As we do more remote sensing science for our users, more people can use it. The more people that use it, the lower cost it is per user. This is how we expand the total addressable market.”
• July 23, 2021: NASA has expanded its contract with two space-based imagery companies, Planet and Spire Global, to broaden access to Earth imagery data and enable scientific research across the federal government. Broader access to this satellite data will help answer questions about how Earth is changing and how those changes may impact people and communities. 18)
- Since 2020, NASA has contracted Planet to provide its employees, grantees and contractors with data for scientific research. The new modification provides access to PlanetScope and RapidEye satellite constellations for U.S. federal civil science agencies, such as the National Oceanic and Atmospheric Administration, the U.S. Geological Survey, the National Science Foundation, and their funded researchers, through NASA’s commercial datasets webpage.
- NASA also expanded its contract with Spire Global to continue its participation in the agency’s Commercial Smallsat Data Acquisition (CSDA) program. Under the contract continuation, Spire will deliver a comprehensive catalog of data from its Earth-orbiting small-satellite constellation. These data will be archived and maintained by NASA as part of CSDA’s Smallsat Data Explorer (SDX) tool and will be available for scientific purposes at no cost to all U.S. federal agencies, NASA-funded researchers, and all U.S. government-funded researchers.
- “The U.S. has a vibrant, capable, and innovate private sector in Earth observation. NASA established our Commercial Smallsat Data Acquisition Program to identify, evaluate and purchase data and imagery from commercial sources that can enhance NASA’s Earth science research and applications,” said Karen St. Germain, director of NASA’s Earth Science Division. “We know that science advances faster and with greater trust when data, analysis, and results are broadly available to the science community. The contracts with Planet and Spire Global are an important step in getting more Earth observation data quickly into the hands of the scientists who help answer the most pressing questions about our home planet.”
- With more than two dozen satellites and instruments observing key climate indicators and how the planet is changing, NASA is the premier U.S. agency for observing and understanding changes to Earth. Commercially acquired data also provides a cost-effective means to complement the suite of Earth observations acquired by NASA and other U.S. government agencies and those by international partners and agencies.
- NASA scientists have previously applied commercial small satellite, or smallsat, data to improve Earth science research. In 2019, researchers used Planet data to better understand the carbon cycle that drives our climate by mapping land surface characteristics in the Boreal region. NASA scientists also used Planet data to monitor Greenland’s ice melt during the 2019 melt season. The access enhanced their understanding of the changes happening on the ice sheet that may have global impact.
- NASA satellites have also investigated the utility data from Spire, which measure signals from Global Navigation Satellite Systems that interact with Earth’s surface and atmosphere. NASA researchers have investigated using these signals to measure the height of ocean and ice surfaces. They have also investigated how these data can improve forecasts of the Earth system using NASA’s atmospheric modeling capabilities.
- Through NASA’s Commercial SmallSat Data Acquisition Program, the Planet contract is awarded until Sept. 21, 2021, with options to extend through Sept. 2023. The Spire contract is awarded until May 2022, with options to extend through Sept. 2023.
• July 7, 2021 (San Francisco, New York): Planet Labs Inc. (“Planet”), a leading provider of daily data and insights about Earth, and dMY Technology Group, Inc.

- Planet delivers a unique data set: a daily scan of Earth’s entire landmass. This data systematically and consistently documents change across the planet on a daily basis. Planet largely operates a subscription-based business model in which customers purchase proprietary data feeds. Planet views its one-to-many model as differentiated, as the data and analytics can be sold multiple times to multiple customers, enabling high profit margins.
- Through this transaction, Planet will invest to accelerate its growth by further expanding into existing and new markets, as well as building additional software and machine-learning-enabled data products and solutions.
- “At Planet our goal is to use space to help life on Earth. We have this huge new dataset — an image of the entire Earth landmass every day — which we serve up via a Bloomberg-like terminal for Earth data, making it simple to consume and expanding reach to potentially millions of users across dozens of verticals,” said Planet CEO and Co-founder Will Marshall. “As the world shifts to a more sustainable economy and more companies and governments set their sustainability and ESG goals, the first step in achieving these objectives is measurement. Planet’s daily, global data is foundational to making that transition. We’re excited to reach this important milestone of taking Planet public to significantly accelerate our mission, and to be doing so with dMY and other great investors.”
- “We believe Planet is a new kind of data company, delivering mission-critical insights and solutions to some of the world’s most influential companies and governmental organizations,” said Niccolo de Masi, CEO of dMY IV. “The Company’s daily, global dataset is impressive and we believe serves as the foundation of a rapidly growing and scalable data-as-a-service subscription business, which we believe is poised for significant growth as data increasingly becomes the fuel that powers the global economy. When you combine their visionary leadership team, talented workforce, vast dataset and transformational technology, it’s an indication that Planet is on a path to become one of the most consequential companies in a generation.”
- “Global sustainability requires data and analytics for global action,” said Marc Benioff. “Planet, and its key initiatives like Carbon Mapper, deliver radical transparency on our rapidly changing climate.”
You Cannot Manage What You Cannot Measure
- Planet data is critical to enabling decisions for many companies as they undergo the data-driven digital transformation. Within governments and across the broader economy, Planet’s daily information feeds are helping to define new methods to monitor resources and account for environmental assets, which is foundational for the ESG transition to enabling a sustainable economy.
- Planet’s data is optimized for machine learning and delivered via a cloud-native platform, transforming the way companies and governments leverage satellite data and derived products, and delivering insights on a daily basis. This powerful dataset is collected by a fleet of about 200 satellites–the largest Earth observation satellite fleet ever–which Planet designs, builds, and operates in house. This constellation captures over 3 million images per day, covering over 300 million square kilometers and generating approximately 25 terabytes of data per day.
- With this data captured and archived every day, Planet has an extensive catalogue of high-resolution Earth images–over 1,500 on average for every point on the Earth’s land mass–providing the ability to go back through time and analyze historical change as well as fuel powerful machine learning applications.
- Planet’s business is enabled by “agile aerospace,” a concept for which the Company was a pioneer. This approach leads to rapidly iterating capabilities in orbit for improved solutions for customers, while dramatically lowering costs compared to traditional aerospace companies. Planet’s vertical integration of satellite design, manufacturing, and operation allows it to cost-effectively develop new data layers and quickly address emerging market requirements relative to other satellite Earth data providers. As new data sets are added, Planet’s products and services enable customers to solve more complex challenges.
- The transaction values Planet at a post-transaction equity value of approximately $2.8 billion. Existing Planet stockholders will retain 77% ownership in the pro forma company and may receive up to an additional 27 million new Planet shares, depending on the performance of the share price during the five year period following the closing.
- Concurrently with the consummation of the transaction, additional investors have committed to participate in the proposed business combination by purchasing shares of Class A common stock of dMY IV in a private placement (the “PIPE”). The $200 million PIPE investment is led by funds and accounts managed by BlackRock, with participation from Koch Strategic Platforms, Marc Benioff’s TIME Ventures, and Google. After paying transaction expenses and paydown of Planet’s existing debt, the balance of the $345 million in cash held in dMY IV’s trust account (assuming no redemptions), together with the approximately $200 million in PIPE proceeds, will be used to fund operations and support new and existing growth initiatives.
- The transaction, which has been unanimously approved by dMY IV’s Board of Directors and Planet’s Board of Directors, is expected to close later this year, subject to approval by dMY IV’s and Planet’s stockholders and other customary closing conditions.
Management & Governance
- Planet’s management team, led by CEO, Co-Founder and Chair Will Marshall and Chief Strategy Officer, Co-Founder and Director, Robbie Schingler, CFO/COO Ashley Johnson and President, Product and Business Strategy, Kevin Weil, will continue to lead the public company following the transaction.

• On 3 September 2020, the Vega rocket rideshare mission successfully lofted 26 SuperDoves, Flock 4v, on Arianespace’s VV16 SSMS-POC (Proof of Concept) flight, along with several other small satellites. The first 14 SuperDoves were successfully deployed into an approximately 530 km Sun-synchronous orbit, and Planet’s mission operations team is already shepherding those satellites through the commissioning process. 24) 25)
- The remaining 12 SuperDove satellites will be deployed into a similar orbit over the next several weeks from D-Orbit’s ION platform, at which point they will join the rest of Planet’s on-orbit fleet. The Flock constellation of Dove and SuperDove satellites provides high-revisit medium-resolution imagery in a variety of spectral bands at a global scale. D-Orbit’s ION will be undergoing its own commissioning process before the remaining SuperDove satellites are to be deployed, and all signs thus far are looking good for a successful completion of the mission.
- The return to launch of the Vega was an especially exciting moment for the smallsat industry given that this was the Vega’s first flight after an unsuccessful launch of FalconEye1 in July of 2019, which was followed by a thorough accident investigation and several corrective actions put into place by Arianespace and Avio, the prime contractor for Vega’s construction. After a handful of subsequent delays due to the COVID-19 pandemic and unfavorable weather conditions, the launcher finally lifted off and proved itself back in flight-shape.
Orbit: Sun-synchronous orbit; target orbit for the 7 microsatellites: altitude of 515 km, inclination of 97.45º; target orbit for the 46 nanosatellites: altitude of 530 km, inclination = 97.51º. The nominal mission duration (from liftoff to separation of the 53 satellites) is: 1 hour, 44 minutes and 56 seconds.

• February 13, 2020: Planet launches every three to six months to keep its constellation of Earth imaging satellites replenished and flying the latest and greatest technologies. Following on the heels of the successful launch of Flock 4p in November of 2019, Planet’s first launch of 2020 will be on Arianespace’s European-made Vega rocket, a first for the Doves. The 26 SuperDoves, Flock 4v, are scheduled for lift-off on March 23, 2020 from the Guiana Space Center in French Guiana (Note: The Vega Rideshare mission launch is delayed due to COVID-19). 31)
- These 26 Flock 4v SuperDoves will be split into two batches on the same launch: 14 of them will be housed inside and deployed from ISL’s QuadPack deployers and the remaining 12 will be deployed from D-Orbit’s InOrbit Now (ION) freeflying deployment platform.
- Over 200 Dove satellites have successfully deployed from ISL’s trusty QuadPack system. This will be the first flight of D-Orbit’s ION system, and those satellites will be deployed over a handful of weeks. D-Orbit will also be verifying key technologies on their ION platform that will eventually enable future versions to act as a “space tug,” with the capability to perform orbit adjustments or accelerate phasing for the satellites it carries.
- Much like the Falcon 9 SSO-A launch in 2018, this Vega launch is going to be a smallsat party. As Arianespace’s official mission name “Small Spacecraft Mission Service—Proof of Concept” suggests, this is the first “dedicated rideshare” on a Vega launch vehicle; rather than a primary satellite customer driving the requirements of the mission, this is a dedicated ride for a few dozen small satellites all looking to go to the same orbit.
- We look forward to a successful launch and extend our thanks to our partners at Arianespace, ISISpace, D-Orbit, Spaceflight and SAB Aerospace for all their efforts in making this mission come together.

• August 2019: Planet is a vertically integrated aerospace and data analytics company that operates the world's largest commercial fleet of remote sensing satellites. Our mission is to image the whole world everyday, and make change visible, accessible, and actionable. We have launched over 350 satellites and built up an automated mission control and ground station infrastructure to monitor and control the satellites, and download the imagery data. Historically, small satellite radios have been downlink limited because of tight size, weight, and power (SWaP) constraints. Rapid prototyping, iteration, and adaptation of the latest COTS technology has allowed for continuous improvements in data throughput on our high speed radio from a very low-cost cubesat platform. Planet's latest X-band radio and antenna solution has achieved a data rate over 1.6 Gbit/s from a 3U CubeSat on-orbit. 34)
Planet's HSD2 (High Speed Downlink 2) is the latest generation compact, low-mass, and low-power radio that was built and deployed on 3U form-factor imaging CubeSats in December 2018. This system operates at X-band and is built using COTS parts with a dual polarization antenna. The two physical channels represent the two polarization modes, right hand circular polarization (RHCP) and left hand circular polarization (LHCP) and each physical channel utilizes 300 MHz of total bandwidth. Within each physical channel, there are three logical channels spaced 100 MHz apart center-to-center frequency. The individual channel symbol rate is 76.8 Msps (Msample/s). Each physical channel has 1 W RF output power and 15 dBi antenna gain. The total DC power consumption of the radio including the processor and the FPGA is 50 Wand the total volume occupied by the radio and antenna, including the mechanical deployment structure for the antenna is 0.25U. The commercial digital television broadcasting standard DVB-S2 is used for modulation and coding. An ACM (Adaptive Coding and Modulation) scheme is used to dynamically change the modulation and coding for each channel individually based on the available link margin. Our ground station network includes 15 dishes (29 dB/K gain-to-noise-temperature) across 5 sites located around the world. The HSD2 is capable of providing downlink volume of over 80 GB during a single ground station pass.
- HSD2 overview: The new generation HSD2 is built on the success of the previous generation HSD Dove radio that operates at 220 Mbit/s throughput. 35) The key features of HSD2 include:
a) X-band operation in the Earth Earth Exploration-Satellite Service (EESS) band (8025-8400 MHz)
b) Dual circular polarization antenna that allows for instantaneous doubling of bandwidth
c) Compact volume of 0.25U including the radio, antenna, and the antenna deployment mechanism
d) DVB-S2 modulation scheme with adaptive modulation (QPSK to 32APSK) and coding rates (1/4 FEC to 9/10 FEC)
e) 50 W total DC power consumption including the processor and FPGA during downlink.
- Satellite Transmitter: The HSD2 satellite transmitter shown in Figure 20 consists of a processor (CPU) and solid state drive (SSD) linked to an FPGA which drives the analog and RF transmitter chains. The FPGA multiplexes the incoming data to six DVB-S2 cores that modulate and provide forward error correction (FEC). Planet's data packets are encapsulated within the DVB-S2 baseband frames. Each DVB-S2 core runs at 76.8 Msps baud rate. The six logical channels are frequency offset and combined into two physical channels and converted to analog baseband using a high-speed DAC (Digital to Analog Converter). Two independent superheterodyne transmitters are used to convert the baseband signals to X-band signals, which are then fed to final stage power amplifiers and right and left hand circular polarized (RHCP/LHCP) antennas for transmission. Table 3 summarizes some of the transmitter parameters. Figure 19 shows the agile and iterative improvements that Planet has made overtime across Dove spacecraft hardware variants.
Figure 19: HSD data rate improvements for various Dove build iterations are shown as blue points on the scatter plot. Triangle represents 100 Mbit/s radio launched on B12 in May 2015, diamond represents the 220 Mbit/s radio launched on B13 in May 2016, and hexagon represents the 1.6 Gbit/s HSD2 radio launched in December 2018 and March 2019 (image credit: Planet)
- Ground Stations and Receiver: Planet operates its own ground network to efficiently meet the data volume needs of our large constellation and for flexibility and agility in the deployment of new technologies. Rapid flexibility is especially important when a new constellation can be built and launched in the same time needed to obtain a license and construct or lease a new ground station. In total, Planet operates 15 owned S/X-band antennas at 5 sites. Figure 21 shows the Keflavik ground station at Keflavik, Iceland and Figure 22 shows the Canadian ground station at Inuvik, Canada. Planet operates telemetry, tracking, and command (TTC) antennas at UHF band from all the S/X-band sites as well as 5 additional sites. Planet's TTC Low Speed Transceiver is based on OpenLST 36) and is also used for time-of-flight ranging. 37) This diversity in assets and locations allows the ground network to scale to meet the demands of both HSD1 and HSD2 radio systems.
- Planet ground stations use COTS components where possible to reduce cost and complexity. All Planet ground systems can support both HSD1 and HSD2 downlinks. Planet's ground station network was originally designed for operating with the single channel HSD1 (Ref. 6). 38) With the addition of multiple channels and dual polarization, the receiver chain has gone through significant hardware and software upgrades. A left-hand polarized feed and low noise block down-converter (LNB) were added to each dish to support the second polarization. The intermediate frequencies were chosen such that the LHCP is combined onto the same coax cable as the RHCP, with appropriate guard bands. Five demodulators were added to the one existing demodulator in each system to interface with the six-channel HSD2 transmitter.
- The demodulators output digital data on a separate 1 Gbit/s Ethernet interface. A COTS network switch bonds these individual channels onto a single 10 Gbit/s fiber optical link that is fed into the ground station server. This approach of maintaining the individual channels on a separate network and multiplexing in the network switch provides the flexibility to change the number of channels or add more channels in the future without significantly altering the existing hardware infrastructure. A block diagram of the HSD2 receiver is shown in Figure 23. If the S/X data throughput exceeds the local network capacity, the ground station will store and then forward the data to Planet's imagery pipeline. Planet's scheduling software takes into account expected data downlinked and limits passes if needed to avoid a backlog of imagery uploads from building up on the local server.
- Channel count and polarization states are stored as configuration variables for both satellites and ground stations, allowing different configurations throughout the network. This makes the network robust as the failure of one or two channel will not impact the remaining channels. Scheduled contacts bring up as many channels that are operational on both the ground station and the satellite. With dynamic per-pass configuration of channels, single-channel contacts (HSD1) become simply a special case of six-channel contacts (HSD2).
- HSD2 Software: The HSD2 software that runs on the satellite and the ground station ensures that the transmitter and receiver work in tandem to optimize data throughput. The low-level software stack makes the six DVB-S2 channels appear to higher level software as single bonded channel. Because of the low error rate of the communication link, the nature of the data being transmitted (mostly images), and the highly asymmetric uplink (S-band uplink speed of 256 kbit/s), a negative acknowledgement (NAK) based protocol is used to transfer files from the satellite to the ground station.
- The ACM (Adaptive Coding and Modulation) feature of DVB-S2 allows for the selection of the appropriate modulation and forward error correction code (MODCOD) from a set of 28 choices that span QPSK through 32APSK modes and 1/4 FEC to 9/10 FEC. The MODCODs can vary on a per channel and per frame basis. Ground receiver and deframer statistics are closely monitored for link margin. The link margin metric in combination with the currently selected MODCOD and an appropriate safety margin are used to choose the MODCOD for the next epoch. This evaluation is performed on a per channel basis.
- While Planet is still bringing our next generation constellation up to full capacity, HSD2 is already showing great results in the production environment. Typical ground stations passes average 400 seconds in duration, and at peak data rates over 1.6 Gbit/s the ground terminal can collect over 80 GB of data per pass.
- While RapidEye satellites will no longer collect imagery for commercial or noncommercial use, their archive of impressive data will remain available to customers, and will be used and appreciated for years to come.
- Customers who use RapidEye imagery will have the option to transition to our Next-Generation PlanetScope products, which will provide higher spatial resolution as well as continuity with the red, green, blue, near infrared and red-edge bands.

- “Over the last three years, Planet data has been used by the combatant commands to support their ongoing missions around the world and to train automated analytic systems to monitor and recognize changes in those operational environments,” said Scot Currie, NGA’s deputy director of Source Operations Group, that falls under the directorate that delivers geospatial data to internal and external customers.
- The Planet subscription contract provides new daily imagery over the U.S. Southern Command area of responsibility and areas of interest in the U.S. Africa Command and U.S. Indo-Pacific Command areas of responsibility.
- NGA also entered into a cooperative research and development agreement with Planet in April 2018, following the purchase of a $14 million subscription for Planet imagery in July 2017 and an introductory contract NGA signed with Planet in 2016.
- Poor weather conditions over Indonesia's Sunda Strait had frustrated spacecraft that view the Earth in the same type of light as our eyes. But the team at Planet has managed to find windows in the cloud. Pictures from its Dove and SkySat platforms show the extent of the volcanic cone's failure.
- It is easier to appreciate now how the island has been reshaped. What was once a crater at the summit of a 340 m-high edifice has been completely broken open to form a small bay.
- Indonesia's disaster agency says more than two-thirds of Anak Krakatau's volume (150-170 million m3) is missing. Much of it is assumed to have slipped into the sea in the colossal landslide that produced the tsunami.
- Earth observation company Planet, which is based in San Francisco, operates one of the world's largest satellite constellations. The big network maximizes the chances of seeing the ground when cloud clears above a target.
- Planet's small Dove spacecraft capture details on the ground larger than 3m - what is termed medium resolution; while its SkySat platforms have a high-resolution capability, capturing details larger than 72 cm.

- Note: The satellite pictures acquired immediately after the disaster came from radar spacecraft, and gave the first hints that volcano Anak Krakatau had collapsed. - Radar instruments can pierce cloud but they return a very different type of view to optical satellites, and need a particular skill to interpret. — It's now thought some 430 people died along the coastlines of Java and Sumatra when the tsunami hit. Thousands more remain displaced.

• December 28, 2018: Twelve Flock -3k 3U imaging CubeSats (each ~ 5 kg) of Planet Labs, were part of the secondary payload launched on 27 December 2018 on the Kanopus-V No 5 and No 6 minisatellite flight of Roscosmos on a Soyuz-2.1a / Fregat-M vehicle from the Vostochny Cosmodrome in Russia. 43) 44)
• December 3, 2018: Three Flock-3s series 3U CubeSats and 2 SkySats were part of the SSO-A rideshare mission of Spaceflight Industries launched on 3 December 2018 (18:34:05 GMT) on a SpaceX Falcon-9 Block 5 vehicle from VAFB (Vandenberg Air Force Base) in California. 45) 46)
• October 04, 2018: NASA has launched a pilot program to evaluate how Earth science data from commercial small-satellite constellations could supplement observations from the agency’s fleet of orbiting Earth science missions. On 28 September, the agency awarded sole-source contracts to acquire test data sets from three private sector organizations. 49)
- NASA’s Earth Science Division in Washington issued blanket purchase agreements for the “Private Sector Small Constellation Satellite Data Product Pilot” program. Under these agreements, the agency purchases data sets and related products based on observations derived from Earth-orbiting, small-satellite constellations designed and operated by non-governmental entities.
- “This pilot program is an innovative and efficient way for us to acquire, examine, and evaluate a wide range of private sector Earth observation data,” said Michael Freilich, director of NASA’s Earth Science Division. “As our very capable NASA research satellite fleet ages and more small satellites are launched by private industry, there are opportunities to leverage the strengths of each into even more complete climate data sets.”
- NASA will provide the test data products to NASA-funded researchers, who will examine whether the data help advance the agency’s science and applications development goals. The pilot program is designed to determine whether these private sector observations and associated products offer a cost-effective means to augment or complement the suite of Earth observations acquired directly by NASA, other U.S. government agencies, and international partners.
- The contracts were awarded to:
1) DigitalGlobe, a Maxar Technologies company headquartered in Westminster, Colorado, has five very high-resolution Earth imaging satellites (GeoEye-1, WorldView-1, WorldView-2, WorldView-3, WorldView-4) capable of collecting 30 cm resolution imagery.
2) Planet, headquartered in San Francisco, has three satellite constellations (SkySat, Dove, RapidEye) with more than 150 satellites supplying imagery and derived products over the entire Earth at medium and high resolution with high repeat frequencies.
3) SPIRE Global, headquartered in San Francisco, operates a constellation of over 60 3U CubeSats collecting radio occultation soundings, aircraft location information and ship reports. GPS radio occultation measurements can be used to sound the atmosphere for temperature, water vapor, and atmospheric pressure.
- These contracts represent the first time that NASA has engaged with commercial small-satellite constellation operators to purchase their data for scientific evaluation. They establish a way for NASA to acquire and examine the data products during the next 12 months. Each contract includes an option for NASA to extend the agreement for an additional four years, for a total value of up to $7 million for each of the three agreements.
- To be considered for participation in this pilot program, companies had to demonstrate they were currently operating a small satellite constellation of no fewer than three satellites in non-geostationary orbit and producing consistent global coverage. Companies also were asked to supply a comprehensive catalog of their data, describing areal coverage, data latency, pricing, and other factors.
- NASA uses the vantage point of space to understand and explore our home planet, improve lives and safeguard our future. The agency’s observations of Earth’s complex natural environment are critical to understanding how our planet’s natural resources and climate are changing now and could change in the future.
• September 12, 2018: Today, Planet is excited to announce the opening of our new satellite manufacturing and testing factory, located in the heart of San Francisco. As part of the grand opening, held in conjunction with the Global Climate Action Summit, the first batch of Doves manufactured in the new facility will be shipped out to India, via our deployment integration partners in the Netherlands, for launch on the PSLV rocket. 50)
- Planet already was home to the most prolific satellite production facility in the world – enabling us to launch a record 146 satellites in 2017. The new facility takes Planet to a new level. At 27,000+ square-feet (2500 m2), the state-of-the-art complex is six times the size of our previous lab and brings all aspects of spacecraft design and production – from R&D to manufacturing to testing – under one roof. This enables us to iterate faster and continue to push the envelope of what small satellites are capable of.
- The additional square footage and flexible floor plan also allows for simultaneous production of multiple spacecraft lines, from Doves to future satellite constellations. For example, concurrent with other spacecraft designs, Planet can now build upwards of 40 Doves per week, which is nearly twice the build capacity of our previous manufacturing site.
- A highlight of the new facility is a multi-purpose environmental testing facility capable of simulating space environments and testing the readiness of our hardware for flight. Coupled with Planet’s expertise in automation and data aggregation, these physical testing capabilities allow us to qualify and release new designs and missions quickly – without compromising quality or agility.
• August 2018: When Planet was founded in 2010, “Mission One” was defined as imaging the entire landmass of the Earth every day. From 2013 onward, Planet launched over 280 Dove satellites (representing 13 design iterations) toward achieving this goal. While many of these satellites have decayed naturally from their LEO orbits, as of June 2018, Planet currently operates approximately 190 Doves (constellation size is dependent on orbit lifetime and replenishment launches) and successfully achieved Mission One in November 2017. 51) 52) Planet is now working toward “Mission Two” – applying machine learning and analytics to imagery to enable users to query what is on the Earth and build customized information feeds – and will continue to launch satellites to replenish the constellation as capabilities improve with future Dove iterations. 53)
- Satellite Operations at Planet: Planet’s Mission Operations team is distributed between the US and European offices. This small team is responsible for maintaining the health of the entire Dove constellation, the scope of which includes commissioning, developing tools for anomaly detection/debugging, performing experiments, and upgrading on board software.
- Maintaining an appropriate balance between health and performance metrics is especially important when managing a large constellation. Planet’s Mission Operations team works closely with subsystem teams. Aside from launch, Planet is vertically integrated from spacecraft design through delivering analytic products to customers, and this allows for efficient collaboration between teams. In the particular case of the ADCS (Attitude Determination and Control Subsystem), Mission Operations maintains and reports on the health of the sensors and actuators, while the ADCS team is responsible for performance: that is, keeping the satellites well-calibrated and making sure the overall pointing and stability metrics are met.
Summary: The ADCS subsystem is integral to the success of a spacecraft carrying out its mission. Calibrating and monitoring this subsystem across a large constellation is challenging, particularly due to the complexities introduced by distributed launches and multiple hardware revisions. Furthermore, as constellations grow in size, both human and material resources can become constrained and need to be allocated appropriately.
Through its experience building and operating the Mission One constellation, Planet has iterated on an system to allow a small Mission Operations and ADCS design team to ensure that imaging specifications are met. Pre-launch calibrations are moved to post-launch operations, using automated maneuvers and processing. Spacecraft performance is monitored through simple visualizations, firstly of product driven metrics, followed by component level metrics. Both these activities are supported by a general bias toward automation and the availability of data retrieval services. All the services are intended to minimize the need for humans-in-the-loop, but where it is required the systems are designed to enable agile decision making. Planet will continue with this mentality as it continues to iterate on the Dove and replenish the constellation.
• June 25, 2018: Planet is expanding its engagement in Europe in a big way. Today, we’re excited to announce a partnership with Airbus, a leader in remote sensing, to enable access to each other’s data and joint cooperation on the development of new geospatial solutions. 54)
- As part of the agreement, Planet and Airbus aim to provide customers with a comprehensive suite of global remote sensing data at multiple temporal and spatial resolutions, and to collaborate on new analytic solutions for a range of commercial markets.
Figure 30: François Lombard, Director of the Intelligence Business at Airbus Defence and Space (left); Dirk Hoke, CEO of Airbus Defence and Space (center); and Will Marshall, CEO and co-founder of Planet (right) at the signing of the agreement at Airbus headquarters in Toulouse, France (image credit: Planet)
- Airbus and Planet are truly complementary partners in the sense that Airbus provides reliable, high-resolution remote sensing capabilities, and Planet brings its unique global coverage and temporal cadence, as well as rapid iteration. Together, both partners will be able to deliver new and sophisticated offerings to fit customer needs globally across markets.
- “By combining our strengths, we will provide a key capability to address all market needs, both in terms of data and value-added products, and to best serve our clients, whatever their industry and their requirements” said François Lombard, Director of the Intelligence Business at Airbus Defence and Space.
- Airbus’s constellation is comprised of very high-resolution Pleiades-1A and -1B; the high-resolution SPOT-6 and SPOT-7 satellites and the DMC constellation. On the radar side, TerraSAR-X, TanDEM-X, and the PAZ radar satellites ensure customers have access to any location whatever the cloud coverage. Planet operates the largest constellation of satellites in history, offering daily, global 3-5 meter resolution imagery via its over 130 PlanetScope satellites and sub-daily, sub-1 meter resolution imagery of anywhere on Earth with its constellation of 13 SkySats.
- Looking ahead, Airbus and Planet can maximize their global presence in key verticals, while leveraging each other’s expertise to bring more comprehensive and advanced geospatial products to market. This partnership spans generations of aerospace innovation and reaches across borders, and Planet is looking forward to a bright future partnering with Airbus.
• January 21, 2018: Today, Rocket Lab's Electron vehicle ”Still Testing” successfully reached orbit and deployed a Dove Pioneer Earth-imaging satellite for launch customer Planet, as well as two Lemur-2 satellites for weather and ship tracking company Spire Global. The Electron vehicle of Rocket Lab lifted off on 21 Jan. 2018 at 01:43 UTC from the Rocket Lab Launch Complex 1 on the Mahia Peninsula in New Zealand. 55) 56)
- Following successful first and second stage burns, Electron reached orbit and deployed Humanity Star, a 1m diameter sphere of Rocket Lab, and the customer payloads at 8 minutes and 31 seconds after lift-off.
- “Today marks the beginning of a new era in commercial access to space. We’re thrilled to reach this milestone so quickly after our first test launch,” says Rocket Lab CEO and founder Peter Beck. “Our incredibly dedicated and talented team have worked tirelessly to develop, build and launch Electron. I’m immensely proud of what they have achieved today.”
- “Reaching orbit on a second test flight is significant on its own, but successfully deploying customer payloads so early in a new rocket program is almost unprecedented. Rocket Lab was founded on the principal of opening access to space to better understand our planet and improve life on it. Today we took a significant step towards that,” he says.
- Rocket Lab’s commercial phase will see Electron fly already-signed customers including NASA, Spire, Planet, Moon Express and Spaceflight. Rocket Lab's offices are in Huntington Beach, California; Washington DC, and Auckland, New Zealand.
• November 30, 2017: A new partnership with the pioneering satellite-imaging and data company Planet will enable Human Rights Watch to increase substantially the organization's use of satellite imagery to document rights violations around the world. 57)
- Satellite imagery plays an increasingly important role in exposing abuses, especially in countries where access for human rights investigators is blocked or heavily restricted, such as Burma or Syria.
- Planet is an integrated aerospace and data analytics company that operates history’s largest fleet of Earth-imaging satellites, collecting a massive amount of information about the changing planet with a core mission of “using space to help life on Earth.” Decision makers in business, government, and nonprofit organizations use Planet’s data and machine learning-powered analytics to develop new technologies, drive revenue, power research, and solve some of the world’s toughest challenges. In November, Planet met its goal of imaging the entire Earth’s landmass every day.
- In recent months, satellite images have played a key role in documenting widespread burning of ethnic Rohingya villages in Burma, attacks against schools in Syria, and airstrikes in populated neighborhoods of Mosul, Iraq. Beyond its use in areas of armed conflict, Planet’s data is uniquely suited for research on abuses related to land rights and the environment.
- Kenneth Roth, executive director of Human Rights Watch, mentioned that Planet’s generous arrangement with Human Rights Watch, with access to its vast collection of high-resolution satellite data, will help provide timely evidence of unfolding abuses in some of the world’s most dangerous spots. This partnership will boost our ability to monitor complex events as they occur and help identify those responsible for atrocities.
- Andrew Zolli, who leads the global impact initiatives at Planet, furthered Roth's comment by adding that Planet seeks to use their groundbreaking technology to promote human rights, protect the Earth, and diminish suffering. As one of the first satellite companies to originate entirely from the civilian sector, Planet is uniquely suited to support Human Rights Watch’s mission of documenting rights abuses wherever and whenever they occur.
• October 31, 2017: Today, 6 SkySats (SkySat 8-13) and 4 Doves (Flock 3m) successfully launched on an Orbital-ATK Minotaur-C rocket destined for a Sun Synchronous, 500 km orbit. Planet is happy to report that all 10 satellites were deployed successfully and that our Mission Control team has made contact with all satellites and begun the commissioning process. 58)
- This marks the 20th launch for Planet and our first-ever dedicated launch, which gave us the ability to choose our orbital parameters and timing of the launch. We sent these 10 satellites to an afternoon crossing time of approximately 13:30 hour to further diversify our product offerings. Most remote sensing satellites operate in morning-crossing configurations, including our currently on orbit set of 160+ Doves and 7 SkySats, and having the world’s largest fleet of medium and high-resolution assets in both morning and afternoon crossing times enables a dataset never before provided in the commercial market at this scale.
- Furthermore, the launch of these 6 SkySats will double the sub-1 meter imaging capacity of our current SkySat fleet, providing a deeper understanding about our changing planet. With this expanded capability, decision makers will gain smarter, more timely insights to solve our world’s toughest challenges.
• October 17, 2017: Newly released satellite images reveal that at least 288 villages were partially or totally destroyed by fire in northern Rakhine State in Burma since August 25, 2017, Human Rights Watch said today. The destruction encompassed tens of thousands of structures, primarily homes inhabited by ethnic Rohingya Muslims. 59)

- Analysis of the satellite imagery indicates both that the burnings focused on Rohingya villages and took place after Burmese officials claimed security force “clearance operations” had ceased, Human Rights Watch said. The imagery pinpoints multiple areas where destroyed Rohingya villages sat adjacent to intact ethnic Rakhine villages. It also shows that at least 66 villages were burned after September 5, when security force operations supposedly ended, according to a September 18 speech by State Counselor Aung San Suu Kyi. The Burmese military responded to attacks on August 25 by the Arakan Rohingya Salvation Army (ARSA) with a campaign of ethnic cleansing, prompting more than 530,000 Rohingya to flee across the border to Bangladesh, according to the United Nations refugee agency.

• August 2017: Planet’s Flock 3p is a constellation of 88 Dove Earth observation nanosatellites launched on a single Indian PSLV (Polar Satellite Launch Vehicle). Commissioning this fleet of satellites is a unique and challenging task that requires significant planning, automation, and operations. At Planet, a small team of operators is charged with shepherding the flock of satellites from initial deployment through full sensor and radiometric calibration. 60)
- Since its founding, Planet has defined and embraced agile aerospace. Planet’s culture encourages iterative development based on experimentation. The operations team has grown and refined the commissioning process through experience on eight different launches.
- Spacecraft operations at Planet also demands a focus on automation. By rejecting the idea that satellites require large teams to operate, the team has built one-of-a-kind automated systems for commissioning and operating large fleets of satellites. Operators focus on improvements and anomalies, not day-to-day operations.
- With 88 satellites deployed from a single rocket, Flock 3p is the largest launch in history. Despite requiring an extensive list of calibration and checkout activities, Planet’s small spacecraft operations team was able to meet its deadlines and have Flock 3p producing imagery for customers in just over three months.
Table 5: Historical Planet launch manifest, including RapidEye and SkySat launches (Ref. 60)
- How Planet Launches: Planet’s ideal imaging orbit is morning sun-synchronous (like most other remote sensing missions). However, Planet’s strategy is to aggressively procure regular launches even if they are not to an ideal orbit. Variability in orbits, such as in power and thermal budgets, is managed through operations and extensive software automation. For this reason, Planet has historically utilized commercial launch services through Nanoracks to provide convenient access to space through the ISS (International Space Station). Flocks are launched as cargo to the ISS and deployed through the J-SSOD (JEM Small Satellite Orbital Deployer) in groups of two. Because the Dove satellites do not have active propulsion, these satellites have an orbit very similar to that of the ISS.
- Planet has also done several direct launches with Doves as a secondary payload to sun-synchronous orbits, which provide the benefit of a consistent sun angle.
Table 6: ISS versus SSO Orbits
- Planet strives for diversity in its launch manifest for a number of reasons. Vehicle family diversity is important because launch failures will usually delay the manifest of that vehicle family by a year or more while an accident investigation is underway. Geopolitical diversity has also proven to be very important to accommodate unpredictable changes in regulations and the global political environment.
• August 2017: Planet has deployed a constellation of low-cost, state of the art small satellites that will effectively act like a line-scanner of the Earth’s surface. Planet’s current mission is to provide images of the entire Earth’s landmass one time per day, every day. The work with the U.S. Navy seeks to expand this global monitoring capability from the land to the sea, starting with coastal regions and expanding into the oceans. Planet’s innovative approach to space is also observed in its image pipeline and rectification processes. Rectification and interpolation approaches are evaluated over water collects to observe how these impact relative geo-accuracies out to 10 km, 60 km, and open water (>=100 km). Analysis revealed relative geo-accuracies of 220 m at 10 km, 221 m at 60 km, and >~1.4 km in open water. 61)
- To date, Planet has launched more than 200 Dove satellites, operates more than 100 Dove spacecraft, and collects and processes more than 150 million km2 of satellite imagery per day. Toward the end of the second quarter of 2017, Planet’s constellation of Doves will revisit every spot on the Earth daily which will include open water areas. Planet complements its imagery collection backbone with an internally developed, web-based, imagery processing platform that enables automated image processing and orthorectification as well as data discovery and delivery.
- In an effort to understand the accuracy of Planet’s products over water, Planet was under contract with the Navy’s Program Executive Office Space Systems via the Rapid Innovation Fund program. The goal is to measure the relative geo-accuracy of the image data sets over littoral (10 km), coastal (60 km) and open water (>100 km). The purpose is to provide an understanding and drive confidence on Planet’s processing pipelines for the addition of maritime imaging to Planet’s commercial product line.
- Under contract with the Navy’s Program Executive Office Space Systems, Planet determined its data relative accuracy over littoral, coastal and open water regions. Planet demonstrated its technical approach and evaluated the relative geo accuracy for the images produced by the Dove spacecrafts. The goal was to drive confidence in Planet’s capabilities to collect over water or in areas where GCPs (Ground Control Points) are not available to provide accurate rectification for the imagery.
- Known relative geo-accuracies over water enables Planet to make collects beyond the Earth’s landmass available to users like the Navy that can benefit from these for its day-to-day operations and mission sets by providing them with unprecedented coverage over water, significantly increasing maritime domain awareness. As a result of the work done through the Rapid Innovation Fund, Planet is in the process of releasing an Open Oceans commercial product. The technical preview for the Open Oceans program went live in June 2017 through which Planet has made several open ocean areas available via the platform.
• July 20, 2017: Planet has won a second contract to provide satellite imagery to the U.S. National Geospatial Intelligence Agency (NGA), taking a sole-source award while UrtheCast, Orbital Insight and Sky Hawk Drone Services offered noncompetitive capability statements. 62)
- The one-year, $14 million contract follows a seven-month, $20 million pilot contract that began in September to assess ways San Francisco-based Planet’s “persistence and global coverage capabilities could most effectively support the NGA mission,” according to a July 19 agency statement.
- NGA said none of the other companies it considered could offer an imagery subscription service with a high enough revisit rate on a global basis. Though others were assessed, NGA told SpaceNews Aug. 1 that Planet received the contract “without competition.”
- NGA said the agency requires the ability to monitor changes across large geographic areas for humanitarian and intelligence missions.
- “Monitoring sources that collect imagery at medium resolution (3-7 meters) at a cadence of weekly or better can satisfy the requirements of making assessments of certain [redacted] intelligence problems, including food security forecasting, [redacted] installation or infrastructure development, military preparedness [redacted] economic forecasting by measuring inventories, and other observations that can be made from analyzing changes over time. In addition, medium resolution monitoring sources improves NGA’s ability to maintain current shoreline data and assess whether foundation products require updating,” the agency said in an unclassified document released July 20.
- Planet’s constellation of remote-sensing cubesats, called Doves, is currently the largest constellation in orbit. The NGA document described the constellation as 160 satellites with 120 active, but Planet spokesperson Trevor Hammond told SpaceNews July 20 that the operator’s current fleet numbers 190 satellites, 142 of which are actively imaging; the remaining 48 are still being integrated into the fleet after launching on a Soyuz rocket last week. Dove cubesats have an average resolution of 3.7 meters. The Planet fleet also includes seven larger SkySat satellites from its acquisition of Terra Bella and five RapidEye satellites from BlackBridge.
- Planet has 23 operational ground stations to communicate with its constellation and receive collected imagery. A ground station completed in northern Canada earlier this year is facing protracted licensing delays, prompting the company to look elsewhere for other sites while awaiting an outcome.
- Of the companies who filed capability statements — meant to inform NGA of what services they can or hope to one day provide — only Vancouver-based UrtheCast is a satellite operator, and the company’s first UrtheDaily satellites won’t be in orbit until early 2019. The company currently leverages cameras on the International Space Station and two free-flyers gained through the acquisition of Elecnor Deimos in 2015.
• May 2017: The Geological Remote Sensing Group (GRSG) has expanded its membership once again with the recent news that Planet — the owners and operators of the world’s largest commercially-operated fleet of satellites — has joined as the Group’s latest corporate member. 63)
- Founded in 2010 by a team of ex-NASA scientists, Planet has designed, built and launched fleets of smallsats to make images of the Earth from space, affordable and widely available, in pursuit of their Mission 1 — to image the entire Earth, every day. With an agile approach to satellite development and Planet’s acquisition of BlackBridge’s fleet of five RapidEye satellites (in October 2015) and recently, TerraBella’s seven high-resolution SkySat satellites, the company has grown their presence in the geospatial industry incredibly quickly.
- Blanca Payas, Planet Sales Director for Europe, Russia and Central Asia explained why Planet decided to join the GRSG by stating that, in a very short time, Planet has become a global company with offices in Europe and the US. More and more, we are finding that our capabilities are supporting projects in the domain of geology. The companies hope to develop new initiatives and activities together.
- GRSG Chairman, Charlotte Bishop, added that Planet’s data and access model starts to challenge the way we in the industry think about and use satellite data in a way not done before.
• April 19, 2017: As Planet of San Francisco announced, it has completed its acquisition of rival satellite imaging company Terra Bella on April 18, it confirmed that Google is now a shareholder in Planet as part of that deal. 64)
- Planet announced on February 3 that it had reached an agreement with Google to acquire Terra Bella. Google had purchased Terra Bella, then known as Skybox Imaging, in 2014 for an estimated $500 million. At the time, both Planet and Google declined to disclose the terms of the deal other than that Google signed a multi-year deal to purchase imagery from Planet.
- The deal, though, was rumored to include Google taking a stake in Planet. In an April 18 blog post announcing that the deal had closed, Planet co-founder and chief executive Will Marshall confirmed that. “We’re also delighted to welcome Google as a shareholder and customer,” he wrote.
- Planet spokesperson Rachel Holm said in an April 18 email that Google took an equity stake in Planet, in addition to the previously announced multi-year imagery contract. Neither company, though, has said how much of Planet that Google now owns.
- The deal closed after receiving regulatory approvals from several federal agencies. “Over the last several weeks, we received all necessary regulatory approvals from NOAA (National Oceanic and Atmospheric Administration), FTC (Federal Trade Commission) and FCC (Federal Communications Commission),” Holm said. The NOAA licenses commercial remote sensing systems in the United States, while the FCC licenses satellite communications.
- The FTC, with the Department of Justice, reviews large acquisitions under the 'Hart-Scott-Rodino Act' for any antitrust issues, setting a waiting period for that review before such deals can close. The FTC issued “early termination” notices March 16 for Planet’s acquisition of Terra Bella and Google’s acquisition of part of Planet, ending that waiting period early and allowing the deal to proceed.
- Planet will now work to integrate the high-resolution imagery from Terra Bella’s fleet of seven SkySat satellites with Planet’s own constellation of nearly 150 satellites that provide medium-resolution images. That fleet includes 88 satellites launched in February on an Indian Polar Satellite Launch Vehicle.
- “This ‘close’ is also the beginning—the beginning of a new chapter at Planet, and of a lot of work across our organization over the next year to make SkySat imagery available on the Planet platform,” Marshall said in his statement. - Holm said that a “significant portion” of Terra Bella’s employees will remain with Planet. The company, headquartered in San Francisco, will maintain an office in Mountain View, California, where Terra Bella was based.

• March 5, 2017: Located at the gateway to the Sahara desert, within the confines of the fertile zone of the Sudan and in an exceptionally propitious site near to the river Niger, Timbuktu (also spelled Timbuctoo) is one of the cities of Africa whose name is the most heavily charged with history. It is an UNESCO World Heritage Site. - The town is the capital of the Timbuktu Region, one of the eight administrative regions of Mali with a current population of about 55,000. 65)
- Founded in the 5th century, the economic and cultural apogee of Timbuktu came about during the15th and 16th centuries. It was an important center for the diffusion of Islamic culture with the University of Sankore, with 180 Koranic schools and 25,000 students. It was also a crossroads and an important market place where the trading of manuscripts was negotiated, and salt from Teghaza in the north, gold was sold, and cattle and grain from the south.
- The three big Mosques of Djingareyber, Sankore and Sidi Yahia, sixteen mausoleums and holy public places, still bear witness to this prestigious past. The mosques are exceptional examples of earthen architecture and of traditional maintenance techniques, which continue to the present time.

• Feb. 23, 2017: The 88 nanosatellites of Planet, launched on Feb. 15, 2017, joined dozens already in orbit, bringing the constellation of "Doves," as these tiny imaging satellites are known, to 144. Six months from now, once the Doves have settled into their prescribed orbits, the company says it will have reached its primary goal: being able to image every point on Earth's landmass at intervals of 24 hours or less, at resolutions as high as 3.7 meters — good enough to single out large trees. It's not the resolution that's so impressive, though. It's getting a whole Earth selfie every day. 66)
- The news has already sparked excitement in the business world, which is willing to pay a premium for daily updates of telltale industrial and agricultural data like shipping in the South China Sea and corn yields in Mexico. But scientists are realizing that they, too, can take advantage of the daily data—timescales that sparser observations from other satellites and aircraft could not provide.
- "This is a game changer," says Douglas McCauley, an ecologist at the University of California, Santa Barbara, who wants to use Planet imagery to map coral bleaching events as they unfold. At present, coral researchers often rely on infrequent, costly reconnaissance airplane flights. "The previous state of the science was, for me, like taking a family photo album and shaking out all the photos on the floor and then being asked to haphazardly pick up three images and tell the story of the family."
- McCauley is participating in Planet's Ambassadors Program, which provides free satellite imagery to researchers as it is collected, with no lag time, under an agreement that prohibits them from reselling the data. Joe Mascaro, a tropical ecologist who runs the program, says it was created in the fall of 2015 in response to queries from scientists yearning for access to the company's growing archive of data. Over the course of 2016, Planet approved the applications of about 160 researchers across a range of fields. "We anticipate there will be many new applications of our data that we didn't anticipate," Mascaro says. The company intends to expand the program in the months ahead, and says it is looking for projects that have social, humanitarian, and environmental impacts—and that have the potential for rapid publication in peer-reviewed journals.

- Andreas Kääb, a geoscientist at the University of Oslo, applied to the program to obtain additional data for his work on glaciers, including an investigation into a massive glacial avalanche in Tibet last July that killed nine herders and hundreds of sheep and yaks. Kääb already had before-and-after imagery from Landsat and Sentinel-2, U.S. government and European Space Agency satellites that have, respectively, 30 m and 10 m resolution and revisit intervals of 16 and 10 days. But higher resolution Planet images provided Kääb with valuable, timely clues. The appearance of large crevasses before the avalanche indicated the glacier was "surging," although surges, typically somewhat slow, don't usually lead to avalanches. But Kääb also saw water pooling on the surface of the glacier—a sign of heavy rainfall or unusually high temperatures. That water might have seeped through the crevasses, soaking the sediments below the glacial bed and creating a lubricant that triggered the sudden slip. When he saw a second nearby glacier with similar patterns, "We warned Chinese authorities, but when our warning arrived the glacier had already collapsed," Kääb says (no people, or yaks, were hurt).
- Kääb also used Planet images to study surface displacements along fault lines in New Zealand following the country's 7.8-magnitude earthquake last November. Though high-resolution GPS ground stations are typically used for this, not all faults have dense GPS networks monitoring them. He used Planet images to determine that two fault lines had slipped between 6 and 9 m — showing that medium-resolution optical satellites can fill the gap.
- Dave Petley, who studies landslides at the University of Sheffield in the United Kingdom, has not joined the Ambassadors Program yet, but says that access to the images would be "transformational" for his research. Orbital imagery has revealed some 80,000 landslides in the wake of the New Zealand earthquake. Aftershocks are likely responsible for many of them. But because available images can be weeks apart, "we just have to assume that everything happened in the main shock," Petley says. Daily images during the sequence of aftershocks would show how the landscape responds to different amounts of shaking, Petley says, and help with disaster response. "You want to know how many of your roads are damaged, how many valleys might be blocked."
- Planet's images are also finding a niche among researchers who deal with human-caused calamities, like deforestation. Matt Finer, a researcher at the Amazon Conservation Association in Washington, D.C., gets weekly deforestation alerts based on Landsat images, but says they are too course to determine whether the damage is natural or human-caused. He now turns to Planet data to decide whether an event is concerning. He recalls one incident when his group spotted 11 hectares of forest loss in Peru, accompanied by extensive dredging—signs of an illegal gold mining operation. "The Peruvian government was on the ground within 24 to 48 hours, kicking the miners out," he says. In previous years, Finer says, hundreds of hectares might be lost before anyone acted.
- Micah Farfour, a special adviser on remote sensing at Amnesty International in New York City, is using Planet images to monitor humanitarian crises as they unfold. Timely images can help her corroborate witness testimony or pinpoint emerging refugee crises. "It's a really, really amazing tool for narrowing down time frames," Farfour says. Still, images acquired from other private satellite companies, like DigitalGlobe, remain crucial to Amnesty's work, because they can offer the 30 cm resolution needed to, say, identify mass graves or count the buildings destroyed in a village that's been burned to the ground.
- Another limitation of Planet's Doves is that they only have four spectral bands—red, green, blue, and near-infrared—compared with Landsat's 11 bands. "Planet's daily observation frequencies are incredibly useful," says David Roy, a remote sensing scientist at South Dakota State University in Brookings and co-leader of the Landsat science team. "But there are lots of things .... that are probably not doable with Planet labs data." A major missing component, he says, are thermal bands in the far infrared, which enable Landsat to monitor the evaporation of water from plants. That's "quite important if you're looking at drought monitoring or water consumption, particularly in agriculture," Roy says. The Doves also lack a shortwave infrared band, which on Landsat can distinguish between different types of vegetation.
- These concerns have not slowed the juggernaut of Planet. In early February, it made two major announcements: It had folded Landsat-8 and Sentinel-2 data into its archive and it had initiated a deal to acquire Google's Terra Bella satellite imaging division and its seven SkySats, which have the capability to image at 0.7 m resolution. However, a spokesperson for Planet declined to say whether scientists will have access to those higher resolution images once the deal is completed.
- In the meantime, as more scientists publish their papers using Planet imagery, word is getting around. Mascaro says he was at a meeting of the American Geophysical Union in December 2016 when Kääb showed how Planet data were enabling the monitoring of glaciers. "Not surprisingly, I got a few Ambassadors applications from people who were in the room."
Table 7: Planet Launches Satellite Constellation to Image the Whole Planet Daily 67)
• On February 15, 2017 (UTC), ISRO (Indian Space Research Organization) launched the CartoSat-2D primary mission from SDSC (Satish Dhawan Space Center) on the east cost of India on the PSLV-C37 vehicle, along with a record number of 103 secondary payloads, among them 88 3U CubeSats, (Doves, 4.7 kg each) of Planet (formerly Planet Labs), San Francisco. The Dutch nanosatellite company ISIS (Innovative Solutions In Space), Delft, The Netherlands, provided the integration service for 101 nanosatellites on this flight. The total launch mass was 1378 kg into a sun-synchronous orbit of 506 km altitude. 68)
- Less than a minute after reaching orbit, the fourth stage released the CartoSat-2D environmental satellite — the mission’s primary payload — about 17.5 minutes into the mission. Ten seconds later, two experimental Indian nanosatellites separated to test new types of sensors to observe Earth’s surface, atmosphere and the conditions in the harsh environment of space. 69)
- Then came a carefully-choreographed deployment sequence for the remaining 101 payloads stowed inside 25 Dutch-built “QuadPacks” for the ride into orbit.
- The QuadPacks opened two at a time to eject their CubeSat passengers. Most of the CubeSats separated while the PSLV was flying over a remote stretch of the Indian Ocean between ground stations in Mauritius and Antarctica. Once the PSLV passed in range of the receiving antenna in Troll, Antarctica, launch controllers at the Satish Dhawan Space Center confirmed all 104 satellites separated as planned.
- The launch of 88 Dove satellites came less than two weeks after Planet announced the acquisition of Terra Bella from Google, which has a constellation of seven higher-resolution spacecraft capable of recording high-definition video during passes over ground targets.

• September 29, 2016: The U.S. NGA (National Geospatial-Intelligence Agency) continues to expand its use of commercial satellite imagery, exemplified by the agency’s recent contract award to Silicon Valley's startup firm Planet, according to Robert Cardillo, the head of NGA. An “introductory” seven-month, $20 million contract to San Francisco-based Planet, formerly Planet Labs, will give defense and intelligence agencies access to the company’s global imagery content. This allows NGA to obtain imagery of at least 85% of the Earth’s landmass every 15 days from Planet. The imagery has many operational uses, including environmental monitoring, augmenting higher resolution capabilities, change detection, and answering intelligence questions. 71) 72)
- NGA has partnered with other “NewSpace” providers over the last year, including BlackSky Global and the Google subsidiary Terra Bella. In addition, NGA and the NRO (National Reconnaissance Office) recently created the joint CGA (Commercial GEOINT Activity) to evaluate new commercial GEOINT data and services.
- NGA is also working with the GSA (General Services Administration) to set up the CIBORG (Commercial Initiative to Buy Operationally Responsive GEOINT) program, which will use GSA schedules and other government-wide contracts “to provide efficient, rapid access” to new commercial imagery, data, analysis and services, Cardillo said. CIBORG is slated to begin executing in early 2017.
- The “centerpiece” of NGA’s commercial imagery program remains EnhancedView, which longtime industry partner DigitalGlobe supports.
• September 2016: The Flock-1 constellation acquired the snow covered Old Crow Flats, deep inside the Arctic Circle, a vast wetland residing within Canada's Vunut National Park (Figure 39). From caribou to grizzly bears, the remote and unspoiled national park plays temporary host to different migratory animals, including waterfowl. 73)

• July 14, 2016: Off the north-eastern coast of Australia, you'll find one of the seven natural wonders of the world, nearly 1,500 miles long, the Great Barrier Reef (Figure 40). One can see from this image the long veins that look like underwater rivers streaming down, giant avenues for all manner of wildlife (and divers) to explore and navigate – established over thousands of years from the seabed up. 74)
• June 17, 2016: The Nazza Lines in Peru are man-made lines and figures in the desert, which are estimated to be between 1500 and 2500 years old. The hundreds of figures vary in form, some of them are simple lines as featured in this image, while others form the shape of animals, people and other life. 75)
- These lines were created by digging shallow trenches in the desert, and removing the red-brown pebbles that coat the Nazca Desert. This made the clear white clay underneath stand out in stark contrast against the ground around the lines. Due to the desert's remote location and arid and windless climate - the Nazca Desert is one of the driest places on Earth - the lines have remarkably been mostly undisturbed in the centuries following their creation.
- The purpose behind the formation of the lines and figures is unknown, leaving scholars with many theories, ranging from astronomical to religious.

• April 14, 2016: The Saint Lawrence River is one of North America’s major shipping channels. The river flows from the Great Lakes Basin into Lake Saint Pierre (Figure 42) — a protected biosphere, home to unique waterfowl — before draining into the Northern Atlantic’s Gulf of Saint Lawrence. 77)
- The cities of Trois-Rivières and Sorel-Tracy sit at either end of the lake, where it rejoins the Saint Lawrence River, and part of Trois-Rivières is visible on the mouth of the river here. Lake Saint Pierre is also a Ramsar site, recognized biosphere reserve and wildlife and bird sanctuary, which is an important area for migrating birds.
• Feb. 2016: Figure 43 of the Flock-1 constellation shows a winter scene in the Sumy Oblast region of the Ukraine. This region is known for its rich earth and agriculture. Come summertime, these fields will produce grains, sunflowers, sugar beets, and potatoes. 78)
• October 26, 2015: Niagara Falls is a famous collection of three waterfalls on the border between the United States and Canada and is situated in the Canadian province of Ontario and the American state of New York. The three individual waterfalls are the Horseshoe, American and Bridal Veil Falls. 79)
- The waterfalls pour forth from the Niagara River, which flows North from the United States into Canada. The river splits into three waterfalls as the water flows around Goat Island (in the center of Figure 44) and a series of smaller islands on its north side. Niagara Falls has become a popular tourist destination over the past 150 years. Some visit the location to witness the power of the torrent of water and enjoy its nearby parks, while others take a more active (and risky) interest, notably including daredevils who have gone over the waterfalls in barrels or crossed the gorge on wires.
- Horseshoe Falls is the widest and deepest of the three waterfalls, and water drops 57 m here. Due to the strength of the current at the waterfalls, this natural source of energy has been harnessed over the years. Power plants have been constructed on or near the falls to take advantage of this, though a treaty was signed in 1950 to limit the use of the falls for this purpose out of concern for conservation of the site.
Figure 44: The Flock 1 constellation acquired this image of Niagara Falls on 26 October 2015. — Niagara Falls is a 12,000-year-old relic of the last Ice Age. Since then, the falls have moved more than 6 miles upstream from their original location near Lake Ontario.
• October 15, 2015: The acquisition of the BlackBridge RapidEye constellation by Planet Labs is now complete. Our energy is now focused on going to market as one team, under a common brand and executing a single global strategy. Over the coming months we’ll role out incremental changes, which will improve our product offerings, service levels and empower our partners and customers to do even more. 80)
• March 1, 2015: The area shown in Figure 45 is in Jeollanam-do, the southernmost province on the Korean Peninsula. This region has some of the most favorable weather for farming, which has resulted in the area producing large amounts of crops. In the small town of Hanja Ri, patchwork grain fields line the shore of an inlet, while intricate rows of seaweed are farmed in the protected waters of the Myeongnyang Strait. 81)

• Feb. 2015: The Chinese city of Ordos (Figure 48), located in Inner Mongolia of China (39°36'N 109°47'E), has gained a reputation for being a "ghost town" due to the small population currently living in the city. Built with the capacity to house over a million people when construction began in 2003, this brand new city was expected to reach that total by 2010, but currently only hosts a population of approximately 20,000 instead. 84)
Due to a variety of reasons, the city was never completely finished, leaving a dichotomous mix of new construction and abandoned sections of the city which were left uncompleted. The price of homes in the city was so high when the construction began that few people could afford it. It is estimated that 98% of the city is either still under construction or completely uninhabited. 85) 86)
Legend to Figure 48: In this image one can see tall apartment buildings and frozen lakes in the Kangbashi New Area, located close to the Ordos Desert.

The Flock 1 nanosatellites will be released, two at time, over a span of one to two weeks early this year. Flock 1 will orbit beneath the station’s ~400 km altitude to prevent any potential collisions. Like the station, the satellites will circle Earth in an orbit inclined by ~51.6º north and south of the equator, flying over most of the planet at some point. From this altitude, the Flock 1 nanosatellites provide imagery with a spatial resolution of 3-5 m. 90)

News update: In November 2014, the FCC (Federal Communications Commission) cleared Planet Labs’ request to launch and operate non-geostationary orbit (NGSO) Earth Exploration Satellite Service satellites. The company plans to launch up to 500 additional NGSO satellites from the ISS (International Space Station) that are physically and technically identical to those previously authorized. 91)
Planet Labs has deployed more than 30 such satellites from the ISS, all of which operate under Call Sign S2912, into circular orbits at altitudes between 380 km and 410 km and an inclination of 51.6º.
The additional satellites were authorized to transmit remote sensing and telemetry data to fixed Earth stations in the 8025-8400 MHz frequency band, receive command signals in the 2025-2110 MHz band, and may use the 401-402 MHz and 449.75-450.25 MHz bands for early phase and emergency-backup telemetry, tracking and command operations.
