Eutelsat 36B (formerlyEutelsat W7) is acommunications satellite in theW series operated byEutelsat. It is co-located withEutelsat 36A satellite at 36° East. It was launched on 24 November 2009, at 14:19:10UTC, by aProtonlaunch vehicle.[1]
Eutelsat andAlcatel Alenia Space announced in December 2006 that the two companies have signed a contract under whichAlcatel Alenia Space will manufacture and deliver the Eutelsat W7 communications satellite.[2] Manufactured byThales Alenia Space in itsCannes Mandelieu Space Center, based on aSpacebus-4000C4satellite bus, it features up to 70Ku-band transponders, 12kW of power, a weight of 5,627 kg (12,405 lb), and has a lifetime of about 17 years (2009-2026).[3]
Eutelsat 36B is one of the most powerful spacecraft in the fleet of Eutelsat.Digital broadcasting anddirect-to-home (DTH) video services is beamed to customers in Russia andSub-Saharan Africa. The new satellite replaced all the capacity on theSESAT 1 (nowEutelsat 16C) satellite, which was redeployed to 16° East after nearly 10 years of operations at 36° East. Eutelsat 36B communications payload is connected to five downlink beams for Europe, Russia, Africa, the Middle East, and Central Asia.
Eutelsat 36B is expected to be replaced byEutelsat 36D, currently scheduled for launch in late 2024.[4][3]
