Eutelsat 36D is a planned new generation multi-mission geostationary telecommunications satellite for Eutelsat, replacing and enhance capacity at 36° East, a key orbital slot for Eutelsat for TV broadcasting (DTH) and government services over Africa, Russia, and Europe. It is based on the Airbus Eurostar-Neo platform, with electric power generation capability of 18 kW, EOR (Electric Orbit Raising) capability, and a launch mass of 5 tons. With 70 Ku-band transponders over five downlink beams and a steerable antenna, Eutelsat 36D provides flexibility and performance optimisation to deliver service in Africa, Russia and Europe for an operational lifetime of more than 15 years.
