Design
The satellite has 29 transponders: 16 C-band, 12 Ku-band and 1 L-band transponders. It was built by Information Satellite Systems Reshetnev (NPO PM) for Kosmicheskaya Svyaz. The communications payload was built by French company Alcatel Space.[4]
Launch
Ekspress-AM3 was launched by Khrunichev State Research and Production Space Center, using a Proton-K / Blok DM-2M launch vehicle. The launch took place at 19:41:00 UTC on 24 June 2005, from Site 200/39 at Baikonur Cosmodrome, Kazakhstan.[2] It deployed into geostationary transfer orbit (GTO) and raised itself into an operational geostationary orbit using its apogee motor.
