GO Kosmicheskaya Svyaz geosynchronous communications satellite, to be assigned to the Ekspress 6A slot at 80E. Replaced the first Ekspress A, lost in a launch failure in 1999. Russian satellite bus with a ommunications payload from Alcatel France. Stationed at 80 deg E.


17 April 2000 Sesat Launch Site: Baikonur . Launch Vehicle: Proton 8K82K / 11S861-01. Perigee: 35,772 km. Apogee: 35,800 km. Inclination: 0.0 deg.

Sesat (Siberia-Europe Satellite) used an MSS-2500-GSO (Gals/Ekspress) satellite bus built by NPO PM of Krasnoyarsk, with an Alcatel Espace France payload of 18 Ku-band transponders. The satellite had 8 Fakel SPD-100 plasma thrusters for stationkeeping. Eutelsat operated their Hot Bird fleet of European television broadcast satellites since the 1980's, but the venture into broadcasting to Siberia represented a new step for them.
