Yamal-402 (Russian: Ямал-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 Ku-band) transponders.[2] It has a design life of 15 years, but reducing to 11 years expected after launch partial failure.[3]

History

In February 2009, Gazprom Space Systems announced a contract with Thales Alenia Space for two satellites: Yamal-401 and Yamal-402.[3] This was the first time a foreign supplier would build a satellite for the domestic Russian market. After much lobby from Russian industry, the contract for the bus and integration of Yamal-401 was cancelled and awarded to ISS Reshetnev, but Thales was allowed to keep the payload supply.[3][4][5]

Launch problem

On 6 November 2012, the satellite arrives at the launch site of Baikonur.[6] On 8 December 2012, at 13:13:43 UTC, a Proton-M / Briz-M launches Yamal-402 to a geostationary transfer orbit (GTO).[7] The same day, Khrunichev State Research and Production Space Center and International Launch Services (ILS) reported an anomaly during the launch in which the Briz-M stage failed 4 minutes before scheduled shut down on its fourth burn.[8][9]

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.[10][11] 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.[12]

Mission

The satellite lost 4 years of fuel to compensate for lower than expected orbit injection.[3]
