Abstract The precise reduced dynamic and kinematic orbits for GOCE satellite have been determined with Position And Navigation Data Analyst (PANDA) software for period of DOY 306 to 332 of 2009.The orbit accuracy is assessed with the following four methods: the differences between the reduced-dynamic orbits and the Precise Science Orbit (PSO) computed by Astronomical Institute, University of Berne (AIUB), the differences between the reduced-dynamic orbits and the kinematic orbits, the 6 hours overlap orbit differences between the reduced-dynamic orbits and the external orbit validation with SLR measurements. The results indicate that the accuracy of the reduced-dynamic orbit is about 1~2 cm in three directions respectively
