SLR Data Analysis
DGFI-TUM routinely analyses Satellite Laser Ranging (SLR) observations to numerous (geodetic) spherical and non-spherical near-Earth satellites. The routine operations, as well as related research tasks, rely on the in-house 'DGFI Orbit and Geodetic parameter estimation Software' (DOGS-OC). Examples for spherical satellites processed at DGFI-TUM are the LAser GEOdynamics Satellite 1 and 2 (LAGEOS-1/-2), Etalon 1 and 2, LAser RElativity Satellite (LARES), Larets, Stella, Starlette, Ajisai, Ball-Lense-In-The-Space (BLITS), GFZ-1, and Westpac-1 (see Figire). All these satellites are orbiting the Earth in altitudes between 600 km and 20,000 km. They are equipped with different types of laser reflectors and differ with respect to diameter and mass. Examples for non-spherical satellites processed at DGFI-TUM are the altimetry satellite missions Topex/Poseidon and the satellites of the Jason family.
