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.

Low Earth OrbitGalaxy 4R, a Hughes HS-601HP or "high power" spacecraft, provides broadcast and telecommunications service to North America, with the capability to provide back-up services to Latin America. The satellite was built on an expedited basis.
Geostationary OrbitThe SESAT 1 (Siberia - Europe SATellite) provides a wide range of telecommunications services over a very large geographical coverage area extending from the Atlantic Ocean to Eastern Russia, including a large part of Siberia. The satellite also provides similar services within the Indian Sub-Continent by means of a Steerable Spotbeam. Sharing the 36° East orbital position with the Eutelsat W4 satellite, SESAT contributes to the development of international, regional and domestic services, such as thin route telephony, corporate and specialised data services and long distance trunk telephony. It facilitates the development of new markets in far eastern Europe and southern Asia for all types of telecommunication and business services, as well as providing full interconnectivity with western and central Europe.
