Jamal 402 ( Russian Ямал-402 ) is a commercial communications satellite owned by the Russian communications satellite operator Gazprom Space Systems.
It was launched on December 8, 2012 at 1:13 p.m. UTC with a Proton-M rocket from launch site 200/39 in the Baikonur cosmodrome in Kazakhstan . After 9 minutes and 15 seconds of flight time, the Briz-M upper stage with the satellite separated from the third stage of the Proton. About nine hours after take-off, the engine of the upper stage switched off at the fourth and final ignition 240 seconds too early, which meant that the satellite did not reach its planned orbit. Roskosmos announced on December 9, 2012 that the systems of Jamal 402 are functioning normally and it is planned to bring the satellite into an approximately circular orbit around the earth with the help of its S400 twin - fuel engine manufactured by EADS Astrium . This maneuver was provisionally completed on December 15, 2012 after a fourth burning phase and the satellite was brought close to its target orbit.
The three-axis stabilized satellite with 46 Ku-band - transponders equipped and will be supplied with its four fixed and steerable beams on the position of 55 degrees East, parts of Africa, Europe, parts of the Middle East and Russia with a wide range of communication services and at the same To take over the services of Astra 1F . It was built by Thales Alenia Space on the basis of the Spacebus 4000C3 satellite bus based on an order dated May 28, 2010 and has a planned service life of 15 years. However, due to the increased drive requirement and the associated fuel consumption, a reduction in service life to an estimated eleven years is expected.
