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).[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.
