Abstract

The HY-2A satellite, launched on October 16, 2011 is the first dynamic environments satellite in China, carrying the SLR tracking system which serve as the baseline tracking system, and in the meantime is one of technology of precise orbit determination. The measurement statistics of HY-2A satellite for the SLR stations, the orbit prediction, and the technological of SLR solution of HY-2A POD are showed, finally the result of the MOE radial accuracy verification for SLR solution of HY-2A satellite is given in this paper.
