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
[edit]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
[edit]The satellite is designed to provide TV and radio broadcasting services, data transmission, multimedia services, telephony, and mobile communications.[1]
Launch
[edit]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]
