Intelsat 805 is a communications satellite operated by Intelsat. Launched in 1998, it was operated in geostationary orbit at a longitude of 55.5 degrees west for around 14 years.
Launch[edit]
The launch of Intelsat 805 made use of an Atlas II rocket flying from Cape Canaveral Air Force Station, Florida, United States. The launch took place at 22:48 UTC on June 18, 1998, with the spacecraft entering a geosynchronous transfer orbit. Intelsat 805 subsequently fired its apogee motor to achieve geostationary orbit.
