• S80/T Spacecraft: Microsat SSTL. Mass: 50 kg.

  An industrial research microsatellite built by Surrey Satellite Technology Ltd (SSTL) for Matra and CNES to carry out 'Little LEO' communications service experiments. Still operational in 2000. S80/T was designed to investigate the technical feasibility of using a constellation of small satellites placed in near-Earth orbit to provide global communications and position location using only hand-held terminals. S80/T was the first fully commercial application of the SSTL multi-mission, modular microsatellite platform developed at the University of Surrey. The same basic platform was also used for the Korean KITSAT-A microsatellite, which accompanied S80/T into orbit on the same launch. The S80/T mission was completed, from concept to launch, within one year and SSTL delivered the platform, associated groundstation equipment and would be providing operations support during the mission within a contract of less than �1M.
