The satellite has a total of 28 transponders, was 9 C-band, 18 Ku-band and 1 L-band transponders. The Ekspress-AM1 Russian domestic communications satellite, built by Information Satellite Systems Reshetnev (NPO PM)) for Kosmicheskaya Svyaz.

Ekspress-AM1 was launched by Khrunichev State Research and Production Space Center, using a Proton-K / DM-2M launch vehicle. The launch took place at 22:11:00 UTC on 29 October 2004, from Site 200/39 at Baikonur Cosmodrome, Kazakhstan.[2] Successfully deployed into geostationary transfer orbit (GTO), Ekspress-AM1 raised itself into an operational geostationary orbit using its apogee motor.
Ekspress-AM1 failed in May 2010 following a shutdown of its attitude-control system. It was recovered, but inclination increased afterwards. On 10 August 2013, the satellite was finally decommissioned and afterwards sent to a graveyard orbit.[1]
