FRANCE, CYPRUS AND GREECE PARTNER TO DEVELOP NEXT-GENERATION SATELLITE OPTICAL COMMUNICATIONS TECHNO
CYPRUS - Operator Hellas Sat, the French Space Agency (CNES), Thales Alenia Space - a joint venture between Thales (67%) and Leonardo (33%) - and Safran have signed a framework cooperation agreement to develop a next-generation optical communications system to be hosted on the future Hellas Sat 5 geostationary telecommunications satellite and the associated Optical ground station to be deployed in Cyprus.
This partnership will deliver ultra-high-performance, very high-throughput data transfer services from geostationary orbit, enabling faster, more secure and more resilient satellite communications for critical applications. It is built on CNES’s SOLiS project1, led by Thales Alenia Space as part of the space component of the France 2030 program, and will demonstrate very high-data-rate laser communications services through the atmosphere.
Under this European cooperation, Thales Alenia Space will supply the SOLiS system and the onboard optical payload for the Hellas Sat 5 geostationary telecommunications satellite. Safran will provide a prototype commercial ("pilot") ground station, which will be installed at Hellas Sat ’s teleport in Cyprus (CyOGS). This pilot station will communicate with CNES’s FROGS station already operating at the Côte d’Azur Observatory on the Mediterranean coast. This communications system will be designed to enable interoperability with other Satellite optical communications systems under development.
Poised to revolutionize satellite telecommunications, free-space optical communications could become a new standard for secure, space-based data transmission, thanks to greatly enhanced capabilities that can deliver data rates on the order of a terabit per second - despite the distances involved and disruptions caused by atmospheric turbulences. It is designed to make intercontinental networks more resilient, as terrestrial and subsea optical fiber links are increasingly subject to sabotage. In this respect, geostationary telecommunications satellites are a proven solution: cost-effective and offering continuous coverage for massive, ultra-secure data transfers between users on the ground.
The cooperation agreement was signed during a special ceremony held at the Battlefield Redefined 2026 Conference (Nicosia, Cyprus), being an event co-organized with DG DEFIS of the European Commission ?n the occasion of the Cypriot Presidency of the European Union. During this significant event, Greek and Cypriot ministers and representatives from Hellas Sat, CNES, Thales Alenia Space and Safran, as well as the National Observatory of Athens, the Hellenic Space Center (the Hellenic Space Agency) and a number of Cypriot and Greek ministerial bodies and governmental authorities, as well as significant space stakeholders, participated thus emphasizing the European character and geopolitical symbolism of the said initiative.
