SBS 1 was a geostationary communications satellite designed and manufactured by Hughes (now Boeing) on the HS-376 platform. It was ordered by Satellite Business Systems, which later sold it to Hughes Communications. It had a Ku band payload and operated on the 149°W longitude.[3]
The spacecraft was designed and manufactured by Hughes on the HS-376 satellite bus. It had a launch mass of 550 kg (1,210 lb), a geostationary orbit and a 7-year design life.[4]
On November 15, 1980, SBS 1 was launched by a Delta-3910 PAM-D from Cape Canaveral at 22:49 UTC.
In June 1990, SBS 1 was finally decommissioned and put into a graveyard orbit.[3]
