Yamal-402 is a Russian geostationary communications satellite. It was launched on 8 December 2012, 13:13:43 UTC from Site 200/39 at the Baikonur Cosmodrome in Kazakhstan.[1] It was built by Thales Alenia Space, and is based on the Spacebus 4000C3 satellite bus. It is equipped with 46 J band (IEEE Ku band) transponders.[2] It has a design life of 15 years, but reducing to 11 years expected after launch partial failure.[3]

Launch problem

On 8 December 2012, Khrunichev Center and International Launch Services reported an anomaly during the launch of the Yamal-402. Briz-M stage failure 4 minutes before scheduled shut down on its fourth burn.[4][5]

On 10 December 2012, specialists from Thales Alenia Space carried out maneuvers to bring the satellite into its designated orbit after a premature separation from Briz-M, the upper stage of a Proton-M carrier rocket.[6]

On 15 December 2012, Yamal-402 was taken to its planned geostationary orbit at the altitude of 36,000 km following a series of four adjustment operations.[7]
