The satellite is based on the Eurostar E2000+ platform. Its payload was 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 2.5 m deployable antennas and one 1.35 m top floor antenna.

Due to success of the satellite, Arabsat let another agreement for an upgraded version of Badr-4 communication satellite: in June 2006, Arabsat gave the contract to EADS Astrium for construction of Badr-6, a high-power broadcast satellite to cover the Middle East and Africa.[1] Badr-6 was launched by an Ariane 5 on 7 July 2008.[4]

Description

This satellite carries 32 transponders in Ku band/FSS & Ku band/BSS. The spacecraft utilizes Astrium's Eurostar E2000+ platform to carry 22 C-band transponders (including eight 52 W moderate power transponders) and 12 Ku band transponders.[5][6]
