Ekspress-AM7 (Russian: Экспресс-АМ7 meaning Express-AM7) is a Russian communications satellite operated by the Russian Satellite Communications Company (RSCC).

Satellite description

[edit]

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

[edit]

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]
