The Geo-IK-2 satellite is a follow-on geodesy mission to the GEO-IK series. It has the following instruments:

  • SADKO radar altimeter
  • Laser retro reflectors
  • GLONASS and GPS receiver
Mission Objectives:
  • construction of high-precision geodetic network in the geocentric coordinate system (reference frame);
  • determination of the Earth's gravitational field parameters
  • determination of continental plates movements;
  • determination of the earth tide;
  • determination of changes in the Earth's rotation speed and pole coordinates, solution of a number of applied problems that require the operative determination of the coordinates of ground stations, including:
    • creation of regional geodetic networks;
    • remote sensing of the Earth;
    • the definition of the marine geoid;
    • ice monitoring.

Satellite laser ranging will be used for Precise Orbit Determination (POD).
