Space Technology Research Vehicle
Space Technology Research Vehicle, or STRV, was a series of British microsatellites which operated in elliptical orbits around the Earth.[3] The series of four satellites, launched as two pairs, were designed to test new technologies in the harsh radiation environment of a geostationary transfer orbit.Each satellite had an expected 1 year life-time and carries myriad detectors, sensors and other equipment for a variety of organisations including the UK MoD, ESA and the US Department of Defense.[3] Several of the STRV satellites' experiments also recorded proton and electron data as they repeatedly passed through the Van Allen Belts.They were launched into orbit to test new solar cells and measure static charge on its surfaces.
