2011 年8 月16 日发射的海洋二号（HY-2）卫星是中国第一颗海洋动力环境卫星，配备的卫星激光测距跟踪系统即作为HY-2 卫星定轨基准系统，同时又是HY-2 卫星定轨系统之一。本文较为详细地介绍了HY-2 卫星激光观测、轨道预报和激光跟踪系统（SLR）定轨技术，并对SLR定轨结果进行了初步检验。

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.
