Wiki

Express-A satellites are designed for operation in the fixed satellite service. Their transponder payloads make it possible to retransmit all types of traffic, including television and radio programming, telephony, data, videoconferencing as well as high-speed Internet. The Express-A satellites are equipped with 17 high-power C- and Ku-band transponders. Russia's Krasnoyarsk-based NPO PM is the prime contractor for the Express-A-series satellites. The satellite bus is developed by NPO PM, while Alcatel Espace of France supplies the payload.
