Based on Airbus Defence and Space's Eurostar E3000 platform, Eutelsat-3B has a tri-band configuration with 51 C, Ku and Ka band commercial transponders. The satellite will replace Eutelsat-3D, which will subsequently be co-positioned with Eutelsat-7A at 7E to provide expansion capacity and enhanced in-orbit security for data, telecoms and video markets in Europe, Turkey and Africa.
