Ekspress-AM7 (Template:Lang-ru meaning Express-AM7) is a Russian communications satellite operated by the Russian Satellite Communications Company (RSCC).

Satellite description

EADS Astrium, was contracted in March 2012, which had become part of Airbus Defence and Space by the time of the satellite's launch, constructed Ekspress-AM7, which was based on the Eurostar-3000 satellite bus.[4] The satellite has a mass of 5,720 kg (12,610 lb), provides 18 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, 36 in the Ku-band and 2 in the L-band.[1] It is a replacemt for Ekspress-AM1.[5]

Launch

Khrunichev was contracted to launch Ekspress-AM7, using a Proton-M / Briz-M launch vehicle - the same configuration that had failed to deploy the similar Ekspress-AM4 and Ekspress-AM4R. The launch took place from Site 200/39 at the Baikonur Cosmodrome, at 22:05:00 UTC on 18 March 2015. The satellite was deployed into the planned geostationary transfer orbit (GTO).[6]
