Abstract: | The “Potsdam-4” program system can model satellite orbits with a high accuracy by means of numerical integration. It takes into account gravitational forces of the earth, the moon, the sun, and non-gravitational forces, and realizes an inertial system with a high accuracy. On the basis of this orbit calculation, geodetic and geodynamic parameters can be determined by means of photographic, laser and Doppler observations. |
