ReOrbit

ReOrbit, headquartered in Helsinki, Finland and founded in 2019, builds software-defined satellites and connected space systems built around the concept of "sovereign" satellite capability, giving governments and militaries independent control over communications and space infrastructure rather than relying on foreign-operated systems.

The company's architecture is modular and hardware-agnostic, allowing satellites to be reconfigured in orbit through software rather than requiring new hardware, and it pairs this with optical inter-satellite links connecting LEO and GEO assets to reduce ground-station dependency and cut latency. ReOrbit manufactures its satellites at its Helsinki facility, which includes one of Europe's largest satellite clean rooms.

ReOrbit's named platforms are Silta, a small-class geostationary satellite system for persistent regional coverage with flexible multi-band payloads, and OrbitCloud, a private regional LEO satellite network offering 3GPP NTN direct-to-device connectivity plus AI inference at the edge via a synchronized, inter-linked satellite mesh. Its customers span military applications (autonomy, secure communications, multi-domain operations) and civil applications (critical communications, commercial connectivity).
