Spacebus is a series of satellite platforms built primarily by Aérospatiale and Alcatel Alenia Space, with parts manufactured by companies like Saab Ericsson Space. They can be equipped with different payloads, but they are most often used as communications satellites. Their typical orbit around Earth is geostationary at an altitude of about 35,800 km with an inclination of 0° to 13° and an orbital period of approximately 1,440 minutes.

The Spacebus 3000 series was built by Aerospatiale[1] and is operated by Arabsat.[1] The Spacebus 3000 orbits at an altitude of about 290 km. The satellite has a mass of about 2,760 kg, which is the earth equivelant to just over 6,000 lbs.[1]

[edit] Spacebus 4000

The Spacebus 4000 series is built by Alcatel Space.[2] Saab Ericsson Space and Alcatel has developed and manufactured the primary structure elements. The Spacebus 4000 is capable of delivering 16 kW of power from 120 transponders. The Spacebus 4000 has many other technological advancements, such as the Avionics 4000, which is based on a 100 volt power bus. The Spacebus 4000 has a mass of approximately 6000 kg, which is the earth equivelant to about 13,200 lbs.[2] The electrical system on the Spacebus 4000 is powered primarily by solar cells.
