Revolv Space, a European manufacturer of high-performance space mechanisms and power generation systems, has secured a new contract with Infinite Orbits, a Toulouse-based satellite integrator that specializes in in-orbit servicing.
A Strategic Leap into Geostationary Orbit
Under this agreement, Revolv Space will supply specialized solar array drive assembly units for several of the integrator’s upcoming geostationary in-orbit servicers.
This contract represents a significant strategic milestone for Revolv Space, marking the company’s first mission to geostationary orbit and its official entry into the high-stakes in-orbit servicing market. Historically, the company has built its heritage in low Earth orbit, where it currently has more than twenty operational units deployed across four separate missions, with several more waiting for integration and launch.
By stepping up to the geostationary market—operating at roughly 36,000 kilometers above the Earth—the company is proving its capability to transition from low Earth orbit platforms to highly demanding, long-duration mission profiles.
Meeting the Demands of Proximity Operations
Operating an inspection and servicing satellite in geostationary orbit presents a vastly different set of challenges compared to low Earth orbit. Spacecraft must withstand a much harsher radiation environment over an extended design life.
More importantly, proximity operations with other geostationary assets demand continuous and uninterrupted power generation. A sudden loss of power during a mid-flight maneuver poses a critical collision risk to highly valuable commercial and government satellites. To meet these stringent requirements, Revolv Space is supplying both engineering and flight models of its SARA Pro system.
This advanced version of their solar array drive assembly is engineered to provide the critical power generation capabilities required for autonomous maneuvers, maximizing the orbit average power for the servicing satellites.
Laurent Hauser, the satellite equipment delivery manager at Infinite Orbits, stated that the company needed a power-generation partner capable of meeting the specific, uncompromising requirements of geostationary servicing, including radiation tolerance and fast delivery at an industrial scale.
Engineering the SARA Pro
The SARA Pro unit is designed to combine three features that rarely coexist in a single mechanism: a compact, microsatellite-class form factor, high power transfer capabilities needed to keep complex payloads running continuously, and a highly radiation-tolerant architecture required to survive the geostationary environment.
The new system builds upon the company’s already qualified SARA Nano version, which successfully concluded its in-orbit demonstration in early 2025. Revolv Space is leveraging results from an extensive radiation testing campaign conducted in 2025, which included total ionization dose and heavy-ion tests as part of their internal research and development programs.
As part of this new contract, the company will also conduct a full geostationary qualification campaign, subjecting the units to rigorous vibration, thermal vacuum, and electromagnetic compatibility tests before flight. This initial collaboration is anticipated to pave the way for a deeper partnership between the two European companies on future missions.
