Geo-IK-2 1 ( Russian Гео-ИК-2 1 , Kosmos-2470 , also Musson-2 , GRAU index : 14F31) was a Russian earth surveying satellite .
The satellite was a successor to the Geo-IK series and was brought into orbit on February 1, 2011 at 14:00:14 UTC with a Rockot with a Briz-M upper stage from launch site 133/3 of the Plesetsk cosmodrome , although not the planned orbit was reached. He could no longer achieve this with his own engines either. The development of the satellite started in 1982 at NPO Prikladnoj Mechaniki . The satellite should be on the Estapheta - satellite bus based, about 4.5 t be heavy and are built around a cylindrical pressure vessel with five meters high and two meters in diameter around. After the collapse of the Soviet Union , however, the development was stopped. In 2001, development was resumed with a much smaller version, in which the pressure vessel was reduced to 1.3 m in diameter and a mass of 900 kg. Many systems (such as the power supply) were taken over from the GLONASS-M satellites. The main instrument on board was a Sadko altimeter from the French company Thales Alenia Space , which was developed from the Poseidon 2 altimeter installed on the French Jason 1 satellite. Geo-IK-2 1 also carried a Doppler system, laser reflectors and a range finder. The second satellite Geo-IK-2 2 to a Miram - microwaves have -Radiohöhenmesser.
Since the Bris-KM upper stage did not ignite a second time as planned, the satellite remained on a transition orbit. Russian Defense Minister Vladimir Popovkin stated that the satellite cannot be used in this orbit. On July 15, 2013, the satellite finally burned up over China.
