S80/T: The Mission

Based on the UoSAT bus, procured by Matra Marconi Space from SSTL. The mission was sponsored by CNES, and was launched on the ARIANE ASAP V52 alongside the micro-satellite KITSAT-1 and the main payload TOPEX-POSEIDON, on the 10th August 1992 (23:08:07 GMT) into a 1338x1315km, 66.1 degree inclined orbit. 

S80/T carried an experimental VHF transponder manufactured by Dassault and weighing 7kg, for characterising the radio environment in the 148 to 149.9MHz band in preparation for the proposed S80 constellation mobile communications and positioning system.

The 50.0kg microsatellite is box shaped with dimensions 350x350x650mm, with four solar panels on the larger facets delivering 25W orbit average, and a 6m gravity gradient boom. 

The spacecraft finally suffered electrical failure due to total dose effects in October 1999.
