The HY-2A satellite, launched on October 16, 2011 is the first dynamic environments satellite in China, carrying the radar altimeter which continues the time series of centimeter lever ocean topography measurement. Orbit error is a major component in the overall error budge of all altimeter satellite missions. The HY-2A satellite carries DORIS deceiver, Dual frequency GPS receiver and Laser Retroreflector Array for Precise orbit determination (POD) to meet 10cm radial accuracy goal for the HY-2A satellite radar altimeter. First, the tracking system and method of POD for HY-2A satellite is introduced, then the solution strategy is showed, finally the results of the radial accuracy for HY-2A satellite are given in this paper.
