Badr-4 is an EADS Astrium
-built communications satellite
operated by Arabsat, launched November 8, 2006 on a Proton-M
/Briz-M
rocket.
It provides fixed satellite communications services in C- and Ku-bands from the 26° East orbital position.
The satellite is based on the Eurostar E2000+ platform and equipped with a payload supplied by Alcatel Alenia Space. The Badr-4-payload consists of 28 active channels in Ku band (16 in BSS and 12 in FSS). Payload power is about 6 kW. The satellite has two 2.5m deployable antennas and one 1.35 m top floor antenna.
Badr 4 is located at 26.0°E. The satellite was a successfully launched from Russia.
Due to success of the satellite, Arabsat led another agreement for an upgraded version of Badr-4 communication satellite: in June 2006, EADS Astrium was awarded the contract by Arabsat for construction of Badr-6, a new high-power broadcast satellite to cover the Middle East and Africa. Badr-6 was launched by an Ariane 5 in July 2008.
