Revolv Space, a European provider of high-performance space mechanisms and power generation subsystems, is proud to announce a new contract award by Infinite Orbits, a Toulouse-based satellite integrator specializing in in-orbit servicing. Under the agreement, Revolv Space will provide solar array drive assembly (SADA) units for several geostationary in-orbit servicers manufactured by Infinite Orbits.
The contract marks Revolv Space’s first mission to GEO and its entry into the in-orbit servicing market, a huge move beyond the LEO CubeSat heritage where the company counts more than 20 units already launched in orbit across 4 missions and several units already delivered, waiting for integration and launch. Under this contract, Revolv Space is currently providing 3 Engineering Models and 4 Flight Models of an advanced version of SARA, named SARA-Pro, suitable for microsatellites and designed to withstand a more challenging radiation environment. This initial contract is anticipated to enable future collaborations between both companies in future missions.
“For some of our servicers, we needed a power-generation partner able to meet the specific requirements of GEO in-orbit servicing, including uninterrupted power supply and radiation tolerance, while supporting fast deliveries at industrial scale. Revolv Space appeared to be the right choice to be able to meet our own multi-missions needs.” Laurent Hauser, Satellite Equipment Delivery Manager, Infinite Orbits.
Operating an inspection satellite in Geostationary Orbit, at roughly 36,000 km, is a different game from Low Earth Orbit (LEO). The platforms must withstand a far harsher radiation environment over a long design life. Proximity operation with GEO assets demand continuous, uninterrupted power generation, as a loss of power mid-manoeuvre introduces collision risks during the maneuver.
This collaboration is Revolv Space’s next strategic move, answering the challenge of bringing proven credibility to the high-stakes GEO market. By supplying units of their Solar Array Drive Assembly (SADA), Revolv Space enables Infinite Orbits to maximize Orbit Average Power (OAP), providing critical, uninterrupted power generation capabilities required for autonomous manoeuvres.
The SADA version being supplied under this contract, named SARA-Pro, is engineered to combine three features that rarely coexist: a compact microsat-class form factor, high power transfer capabilities needed to keep payloads running continuously, and radiation-tolerance capabilities to survive the GEO environment. SARA-Pro builds upon the already qualified version of SARA-Nano, currently being delivered to another commercial customer, and the lessons learned during its In-Orbit Demonstration of SARA, successfully concluded in early 2025. Revolv Space will also leverage the results of the TID and heavy-ion test campaign performed in 2025 as part of its internal SADA R&D programmes. In addition, as part of the contract, Revolv Space will perform a full GEO qualification campaign, including vibration, thermal vacuum and electromagnetic compatibility tests.
“Going to GEO with Infinite Orbits is a turning point for Revolv Space… and truly exciting! It validates our ability to take what we have proven in LEO and apply it to one of the most demanding mission profiles. In-orbit servicing is where space infrastructure is heading, and we intend to be the power-subsystem partner satellite integrators like Infinite Orbits can rely on.” Filippo Oggionni, Chief Commercial Officer and Co-Founder, Revolv Space.
