The S80/T satellite was built for CNES by Matra Marconi Space using the Surrey Satellite Technology Microbus (Uosat) bus. The 0.35 × 0.35m, 50 kg satellite had a 6-m gravity gradient mast. It was launched on 1992 Aug 10 on an ASAP Ariane from Kourou. S80/T carried an experimental 148/138 MHz transponder for tests of mobile communications and location-finding for a proposed, but later abandoned, LEO constellation named S80 or Taos.
The spacecraft finally suffered electrical failure due to total dose effects in October 1999.
