Ekspress-A1 (Russian: Экспрeсс-А1 meaning Express-A1), also designated Ekspress-6A No.1, is a Russian communications satellite which is operated by Russian Satellite Communications Company (RSCC).

Satellite description

It was constructed by NPO Prikladnoi Mekhaniki (ISS Reshetnev) and Alcatel Space and is based on the MSS-2500-GSO satellite bus. It is equipped with seventeen transponders.

The satellite was launched at Baikonur Cosmodrome at Site 200/39 on 27 October 1999, at 16:16:00 UTC. The launch was made by Khrunichev State Research and Production Space Center, and a Proton-K / DM-2 launch vehicle was used. It is part of the Ekspress satellite constellation.
