Ekspress-AM8 (Russian: Экспресс-АМ8 meaning Express-AM8) is a Russian communications satellite which was launched in 2015. Part of the Ekspress series of geostationary communications satellites, it is owned and operated by the RSCC Space Communications.
Satellite description
Thales Alenia Space, constructed Ekspress-AM8 payload, and ISS Reshetnev constructed the satellite bus which was based on the Ekspress-1000NTB. The satellite has a mass of 2,100 kg (4,600 lb), provides 5.9 kilowatts to its payload, and a planned operational lifespan of 15 years. The satellite carried 62 transponders: 24 operating in the C-band of the electromagnetic spectrum, 12 in the Ku-band and 2 in the L-band.[1]
Mission
The satellite is designed to provide TV and radio broadcasting services, data transmission, multimedia services, telephony, and mobile communications.[1]
Launch
Ekspress-AM8 was originally to be launched in 2012 or 2013 into RSCC's 14° West longitude, but was delayed to 2015. It used a Proton-M / Blok DM-03 launch vehicle to be inserted directly into geostationary orbit.[3]
