Spacens develops the Kaon project: small & serially produced GEO communications satellites — a versatile and economical alternative to conventional multi-tonne spacecraft.
The GEO arc provides a perfect geometry for broadcast services: a satellite fixed in the sky allows continuous communications with simple, mass-produced terminals, and the distance to Earth from GEO lets a single satellite permanently cover a large geographical footprint. Historical operators built on this geometry during the golden age of satellite TV broadcast.
That golden era ended as point-to-point applications progressively displaced broadcast. The historical industry capitalized on its large GEO platforms with a multi-spot “high-throughput satellite” concept, spreading capacity evenly across the Earth's surface — a geometry increasingly misaligned with real, concentrated traffic demand. High-throughput satellites deliver impressive theoretical throughput figures, but ones increasingly disconnected from ground-segment constraints and requiring ever-increasing complexity.
This mismatch is why we chose a different path: instead of large, capacity-limited GEO satellites constrained by spectrum, our long-term vision is fleets of small, affordable satellites organized in clusters, surgically bringing capacity where it's needed. The roadmap starts with Kaonite, our first-generation satellite design, bringing sovereignty to nations and defense organizations while scaling the company ahead of a more ambitious second generation that fully delivers on this vision. The feasibility of both satellite designs has been confirmed by two consecutive CNES studies.
Spacens is active across every domain of satellite communications.
Spacens already supports Newspace and historical industry players, and institutions, in the frame of their space project developments. Our capabilities cover the full spectrum of skills needed to develop a SATCOM space project:
Spacens develops various types of on-board communication systems to be integrated on customers' satellites:
Thanks to the extensive experience of its staff and the knowledge of its industrial suppliers, Spacens delivers on-ground integrated systems and end-to-end testing during satellite integration, test, and in-orbit operations — with complete validation plans securing the ground-to-board interface.
Beyond consulting and on-board systems, Spacens is building its own satellite family: Kaon — our long-term vision for a fleet of small, sovereign GEO satellites, starting with Kaonite, our first generation.
Discover the Kaon project →We are a team of telecommunications satellite industry veterans with backgrounds at Thales Alenia Space, Arianespace, Intelsat, Rascomstar and SSC.
30 years of satellite, payload, and SATCOM systems experience.
LinkedIn →40 years of satellite contracts, insurance, and negotiation experience.
12 years of launch vehicle, structure, and AIT experience.
40 years of payload, telecom, and RF engineering experience.
Our small and dedicated structure acts as prime contractor to lower the cost of design development and prime contracting. We expect to reach around 50 employees at steady state.
Geographical proximity of the consortium members' teams and facilities in France optimizes the industrial, assembly and test phases — a secured integration and test sequence relying on proven facilities while offering an optimal economy:
Spacens partners with Impulse Space for direct-to-GEO rideshare, launching Kaonite satellites together to orbit.
