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. Satellite descriptionThe spacecraft was designed and manufactured by Hughes on the HS-376 satellite bus. It had a launch mass of {{convert|1,117|kg|abbr=on}}, a geostationary orbit and a 7-year design life.[4] HistoryOn 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.
