Geo-IK
Part of KAUR-1 Family
Geo-IK
Geo-IK
Russian earth geodetic satellite. Development of a second generation geodetic satellite system began in 1977. Geodesy satellite built by NPO Prikladnoi Mekhaniki (NPO PM), Russia. Launched 1981 - 1994. Used KAUR-1 bus.

AKA: 11F666;Eridan;Musson. Status: Operational 1981. First Launch: 1981-01-23. Last Launch: 1994-11-29. Number: 14 . Gross mass: 1,600 kg (3,500 lb). Height: 3.00 m (9.80 ft). Span: 2.04 m (6.68 ft).

From 1977 to 1978 NIU MO (50-TsNII KS and 29-NII VTS) headed the development effort, with the prime contractor being NPO PM under Reshetnev. The Geo-IK/Musson satellite was used to develop a unified world geodetic data base and geocentric co-ordinate system. It characterized the earth's geoid and gravitational field for navigation systems. Flight trials began in 1981.

GEO-IK was the final KAUR-1 bus spacecraft with 'wrapped' panels on a cylindrical body. While it used the standard pressurized instrument container and gravity-gradient single-axis passive orientation system, it was much heavier than earlier spacecraft, with more elaborate systems and a deployable outer sheath of solar cells. It provided five ways for determining satellites position:

  • Doppler system working at 150 and 400 MHz and providing 3 cm accuracy
  • High intensity lights flashing 3 times per second, allowing precise location by ground observatories
  • Radio transponder working at 5.7/3.4 GHz and providing 5 m accuracy
  • Laser reflectors providing 1.5 m accuracy
  • Radar altimeter working at 9.4 GHz providing 5 m altitude accuracy. This was equipped with a separate autonomous system for accurate pointing.
