SBS 3 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 94°W longitude.
The spacecraft was designed and manufactured by Hughes on the HS-376 satellite bus. It had a launch mass of 1117kg (2,463lb), a geostationary orbit and a 7-year design life.
On November 11, 1982, SBS 3 was finally launched by a Space Shuttle Columbia in the mission STS-5 from Kennedy Space Center at 12:19 UTC. The satellite was launched along with the Canadian communications satellite Anik C3.
On 2 June 1995, SBS 3 was finally decommissioned and put on a graveyard orbit.
