The Spanish startup company Sateliot on July 28, 2020, selected Open Cosmos (UK) to build and operate a constellation of up to 100 small satellites, but stopped short of a firm contract for the full system. 1)

Sateliot is raising funds to build the constellation, designed to connect sensors and devices from low-Earth orbit. The company has raised 2.4 million euros ($2.8 million) since forming in 2018, and hopes to raise a 7-million-euro Series A this year to fund three demonstration satellites, Sateliot chief executive Jaume Sanpera told SpaceNews.

Sateliot estimates it needs $35 million to deploy an initial 16 satellites by the end of 2022, he said, not counting the demonstration satellites. An exact amount for 100 satellites has not been determined, he said.

Open Cosmos of Harwell, United Kingdom, is under contract to build two demonstration satellites for Sateliot, said Rafel Jordá, founder and chief executive of Open Cosmos.

The first satellite is a 3U CubeSat scheduled to launch late this year, Jordá said. A form factor for the second demonstration satellite has not been finalized, he said.

Sanpera said that while Sateliot chose Open Cosmos for its first two prototypes and subsequent constellation, it will openly compete its third prototype with other manufacturers.

Open Cosmos builds CubeSats and smallsats up to 50 kg, but its business model centers on turnkey solutions for customers, Jordá said. For Sateliot, the company is arranging launches, ground station communications and insurance, and will operate the satellites in addition to building them, he said.

Sateliot is designing its satellites to fill gaps for 5G mobile network operators, providing roaming services for sensors and devices on trucks, precision agriculture equipment, clean energy infrastructure and other sectors, Sanpera said. The company signed an unfunded memorandum of understanding with the European Space Agency in January to collaborate on integrating space and terrestrial 5G solutions.

Open Cosmos Ltd. is working on the construction, mission management and launch preparation of the first Sateliot nanosatellites. In July 2020, Open Cosmos has sealed a deal with satellite communications operator Sateliot of Barcelona, Spain, to build and operate their nanosatellite constellation, enabling continuous global connectivity for Internet of Things (IoT) under the 5G architecture. 2)

Open Cosmos is already underway in the manufacturing, mission management and launch of the first satellites, out of the one hundred which comprises the full constellation, that Sateliot has scheduled for construction before the end of 2022. These nanosatellites operate in low Earth orbit, flying at an approximate altitude of 500 km to guarantee IoT connectivity at a global scale and in almost realtime.

The forecast for the next two years is that there will be more than 50 billion IoT devices globally and with this constellation Sateliot is perfectly positioned to partner with conventional telecommunication providers to ensure ubiquitous coverage.

Sateltiot will also offer monitoring and tracking systems, data analysis and processes in areas such as: maritime, railways, aeronautical, agriculture & farming, oil & gas exploration, electric or critical infrastructure.

Rafel Jordá, Founder and CEO of Open Cosmos, said "We are excited to have satellite production underway for these satellites and to be progressing with all other aspects of the mission, including system integration, launch, licensing & logistics, as well as orbit operations. We are delighted to partner with Sateliot to enable the reality of IoT anywhere".


Development status

• March 22, 2021: Today, the first nanosatellite, named Enxaneta, of the Catalan Government (Generalitat de Catalunya) took off at 7:07:12 am (CET), from the Baikonur Cosmodrome, in Kazakhstan. This is the first of several nanosatellites that the Catalan Government will put into orbit in the framework of the NewSpace Strategy for Catalonia. 3)

- The data will initially be used by the departments of the Catalan Government, with the aim to open data access to universities, research centers, technology centers and companies, later on. Among other applications, the data will be used to monitor the flow of rivers and water reserves throughout the territory, improving water management; to monitor and protect wildlife; to receive weather data from stations located in remote locations; to monitor soil movements to anticipate natural disasters and to monitor livestock and crops to detect disease and define more efficient strategies.

• January 2021: Sateliot, the satellite telecommunications operator that will launch the first nanosatellite constellation to democratize the IOT with 5G coverage, will provide its expertise in 5G satellite communications in a secure information exchange project for banks, security agencies and governments worldwide. 4)

- This project, called Quango, has been supported by the European Commission with € 2.1 million of funding and involves research centers such as ICFO (Institute of Photonic Sciences) in Barcelona, as well as international universities such as Malta's University, the Sorbonne in Paris and Padova in Italy, and companies with expertise in the space sector.

- Quango's objective is to design and demonstrate in the laboratory a satellite with a double payload which will, on the one hand, enable 5G connection and, on the other, introduce an end-to-end encryption device using the QKD (Quantum Key Distribution) technique. This system will thus allow the secure exchange of information between organisms located thousands of kilometers away, the size of a microwave, which will fly at an altitude of about 600 km.

- To make this possible, Sateliot will use all the expertise acquired in the design of its nanosatellite constellation for IOT with 5G and will support the integration of this technology into a device capable of generating and exchanging security keys using the laws of quantum physics. In addition, it will develop the study of its application with a European bank.

- The secure exchange of sensitive information is of crucial importance in our society because, among other things, it protects the transfer of money, commercial transactions, medical data, remote control of critical infrastructures (electricity network, telecommunications, etc.) from all kinds of external interference.

- In the future, this project could also represent an opportunity for Sateliot, as the company sees the possibility of taking advantage of its nanosatellite constellation to house both this encryption system and its IOT systems, as a way of optimizing both missions.

- According to Marco Guadalupi, Sateliot's CTO, "the European Commission's support for this project is a very important step in the implementation and development of 5G by satellite with applications as important as this one. Furthermore, this effort in research and innovation may represent a new way of optimizing and making even more efficient the satellite missions in which we are currently working to make a global and massive IOT with 5G coverage possible".

- Sateliot is the first satellite telecommunications operator that will provide global and continuous connectivity to all the elements that make up the universe of the Internet of Things (IoT) – such as the connected car or home – under the 5G protocol. Thanks to a constellation of nanosatellites of the latest generation, located at low altitude and acting as mobile towers, Sateliot is the perfect complement to the large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not reach.

• November 2020: The International Telecommunication Union (ITU) has approved Sateliot's plan to launch a constellation of 100 nanosatellites for Internet of Things (IoT) connectivity. Sateliot announced in November that it is now permitted to coordinate the frequencies of its nanosatellite constellation with telecom operators. The company now plans to begin a round of talks with the space operators and public administrations to ensure frequency compatibility. 5)

- Sateliot, which is based in Spain, is planning to build a constellation of nanosatellites at low altitudes that act as mobile towers in space as a complement to telcos to provide connectivity for the IoT beyond the limits of terrestrial infrastructure, under 5G protocol.

- In addition, the 3GPP working group for non-terrestrial IoT networks also plans to discuss a Sateliot proposal to include a scenario for LEO nanosatellite networks providing IOT services in the definition of the 5G standard.

Launch: The first Sateliot nanosatellite, a 3U CubeSat, was launched as a passenger payload on 22 March 2021 (06.07:12 UTC) on a Suyuz-2.1a vehicle, operated by GK Launch Services from the Baikonur Cosmodrome, in Kazakhstan. 6)

Orbit: Sun-synchronous orbit, altitude of ~550 km.
