摘　　要：地面站是卫星导航通信系统中必不可少的重要组成部分,具备接收、发射信号,监控卫星以及与地面通信网络通信交换等功能,地面站的大天线对星跟踪是卫星通信开展的基础。针对卫星地面站的重要性,介绍了CAPS(中国区域定位系统)位于北京的卫星通信地面站天线对星跟踪系统,利用该天线对准亚太I号卫星时的方位角、俯仰角以及系统AGC电平值分析了亚太I号卫星的运动轨迹,亚太I号卫星的漂移幅度在不断的增大。Ground satellite station is an important part of the essential for satellite navigation and communication systems, which has the function of receiving and transmitting signals, monitoring satellite and exchanging information with the communications network on the ground, the large ground station antenna aligns satellite is the base for satellite communications system. For the importance of satellite ground station, satellite tracking is carried out based on this article in Beijing using CAPS （Chinese Area Positioning System） satellite communications ground station 16 m antenna aimed at the Asia-Pacific-1 satellite azimuth, elevation and system AGC level value analysis the trajectory of the Asia-Pacific-1 satellite trajectory, the Asia-Pacific-1 satellite drift rate is increasing
