The Tempo satellites were owned by TCI Satellite Entertainment Inc. (TSAT), a subsidiary of TCI (Telecommunications Inc) of Littleton, Colorado, and provided high power direct TV broadcasting for the United States. It uses the SS/Loral FS-1300 bus.
The launch of TEMPO 1 was delayed; A last minute FCC ruling that it could not use a Canadian orbital slot and frequencies caused the payload to be reduced from 27 to 11 transponders. Once regulatory problems were resolved, the processing flow for TEMPO 2 was in better shape to allow launch and so it went first. TEMPO 2 launch mass was 3558 kg. It will use the 119W slot.
A month after launch, Tempo 2 suffered a power failure during a solar storm, leaving it operating at 85 percent power. Tempo 2 had the first GaAs arrays on a high power comsat. Loral reported later that solar arrays wired at more than 60V were prone to electrical discharges and short circuits during moderate solar activity.
Tempo 2 became the property of DirecTV/El Segundo in 1999. It was renamed DirecTV-6.
