Space Technology Research Vehicle, or STRV was a series of British microsatellites which operated in elliptical orbits around the Earth. The satellites were built by the Defence Research Agency at Farnborough, for the UK Ministry of Defence.[3]


Built by the DRA, the satellites were designed to test new technologies in the harsh environment of an orbit. Each satellite had an expected 1 year life-time and carries myriad detectors, sensors and other equipment. The satellites were controlled from the DRA groundstation in the UK.[3] The STRV satellites' experiments measured various environmental variables in the upper atmosphere.[4]


Two satellites were launched in June 1994 and another two were launched in November 2000, from the space center in French Guyana.[5]

STRV 1A & 1B[edit]

STRV 1A and STRV 1B are cube-shaped mini-satellites each with a mass of 50 kg. They were launched into orbit to test new solar cells and measure static charge on its surfaces.[6]

STRV 1C & 1D[edit]

STRV 1C and STRV 1D both have a mass of 100 kg and carry test technology devices including lithium ion batteries and a GPS receiver.[6]

Current Status[edit]

The satellites form a part of the growing amounts of orbital debris in orbit of Earth.
