A US Space Force technology demonstration satellite hosted on a geostationary platform as part of the Space Technology Program. STPSAT-6 tests advanced communications technologies, space environment sensors, and experimental payloads in the harsh GEO radiation environment. The STPSAT program provides a flight-test pathway for emerging technologies before they're incorporated into operational military satellites.
