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).[3]
Eutelsat W4
Following its launch and on-orbit testing, it was placed in geostationary orbit at 36° East,[4] 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.[2]
