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
In February 2009, Gazprom Space Systems announced a contract with Thales Alenia Space for two satellites: Yamal-401 and Yamal-402.[4] This was the first time a foreign supplier would build a satellite for internal Russian market. After much lobby from local industry, the contract for the bus and integration of Yamal-401 is cancelled and awarded to ISS Reshetnev, but Thales is allowed to keep the payload supply.[5][6][7]
On November 6, 2012, the satellite arrives at the launch site of Baikonur. [8] On December 8, 2012 13:13:43 UTC a Proton-M/Briz-M launches Yamal-402 to a geostationary transfer orbit. [9] The same day, Khrunichev Center and International Launch Services reported an anomaly during the launch in which the Briz-M stage failed 4 minutes before scheduled shut down on its fourth burn.[10][11]
On December 10, specialists from Thales Alenia Space carried out maneuvers to bring the satellite into its designated orbit after a premature separation from Briz-M. [12][13] On 15 December 15, Yamal-402 was taken to its planned geostationary orbit at the altitude of 36,000 km following a series of four adjustment operations.[14] The satellite lost 4 years of fuel to compensate for lower than expected orbit injection.[15]
