Badr-4 (a.k.a. Arabsat 4B) is an EADS Astrium-built communications satellite operated by Arabsat, launched 8 November 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. 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.

Badr 4 is located at 26.0°E. The satellite was launched from Russia.

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. Badr-6 was launched by an Ariane 5 on 7 July 2008.

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.
