Satellite connectivity is becoming a decisive factor across all modes of transport—planes, trains, land vehicles, and beyond.
The recent announcement of a partnership between Air France and Starlink, understandable given the American provider’s technological lead, has sparked much debate.
SNCF is now exploring options to deliver high-speed internet on board its trains. This is a legitimate move, as passenger expectations continue to rise, but it also raises a deeper strategic question. At a time when the French President and, soon, the European Union are investing heavily in Eutelsat-OneWeb and preparing the launch of IRIS², it is more essential than ever to prioritize sovereignty—even on the ground.
Sovereign solutions are already here
Greenerwave, a deeptech company specializing in the control of electromagnetic waves, is developing a passive, energy-efficient, multi-orbit antenna—100% designed and manufactured in France. Compatible with all constellations (LEO / GEO), the antenna has been engineered for demanding mobile environments: trains, aircraft, autonomous vehicles, or tactical missions.
It delivers:
- Up to 10 times lower energy consumption compared to conventional systems
- Unmatched mechanical and thermal resilience (operating from –40°C to +60°C)
- Native compatibility with OneWeb, IRIS², and future constellations
“We welcome the State’s decision to strengthen its stake in Eutelsat-OneWeb. But we must go all the way in embracing a sovereign logic. Today, France has the capabilities to design, produce, and industrialize antennas that are low-impact, robust, and high-performance. That is precisely what we’re doing at Greenerwave”, said Geoffroy Lerosey, CEO and co-founder.
Geoffroy Lerosey is available for interviews and commentary on:
- The stakes of sovereign SATCOM for mobile connectivity
- France’s strategic role in the terminal market
- Live demonstrations of antennas in Paris or Toulouse
Recent milestones:
- A strategic contract with the French Armed Forces
Greenerwave was awarded a €10M+ contract to equip the French military with next-generation SATCOM terminals. Led by Airbus Defence and Space, this major program also involves Eutelsat-OneWeb. The objective: to validate sovereign Ka/Ku-band terminals for Satcom-On-The-Move applications, supporting the transformation of military communications.
- A partnership with Safran Passenger Innovations (SPI)
Greenerwave and SPI are collaborating on a revolutionary Ka-band terminal for in-flight connectivity. This solution is low-power, cost-efficient, and constellation-agnostic, supporting the aviation industry’s shift toward sustainable, future-proof.
