Eutelsat W4

The W satellites are designed to provide telecommunications services primarily over Europe (W1, W2, W3, W3A and W5) and communication services over Russia and Africa (W4). Eutelsat W4 is designed to provide 31 transponders at saturation. The W satellites have a minimum operational lifetime of 12 years. The spacecraft is based on the Spacebus-3000B2 platform.

The W4 satellite provides a high-power broadcast coverage of Western Russia with a total of nineteen channels. In addition, the satellite provides a wide-area African coverage and a high-power Steerable coverage. The African coverage includes the majority of central and southern Africa. In its nominal operational position, the Steerable coverage provides a high power coverage of West Africa. Six channels are connected to each beam on the downlink, giving a total of thirty-one operational channels. The satellite design allows transmission from the Steerable coverage to the African coverage and vice versa, permitting, for example, simultaneous broadcasting to both coverages.
