Eutelsat 36A (formerly Eutelsat W4 and Eutelsat 3 F-4) is a French communications satellite operated by Eutelsat Communications. It was constructed by Alcatel Space and is based on the Spacebus-3000B2 satellite bus.

Launch

Eutelsat W4 was launched on the maiden flight of the Atlas III launch vehicle, which used the Atlas IIIA configuration. The launch was contracted by International Launch Services (ILS), and occurred on 24 May 2000, at 23:10:05 UTC from Space Launch Complex 36B at the Cape Canaveral Air Force Station (CCAFS).

Eutelsat W4

Following its launch and on-orbit testing, it was placed in geostationary orbit at 36° East, from where it provides communications services to Russia and Africa. It carries thirty-one transponders, and has an expected on-orbit lifespan of 12 years.

Eutelsat 36A

In December 2011, Eutelsat announced, that their satellite assets will be renamed under a unified brand name effective from March 2012. This satellite became Eutelsat 36A.
