摘　　要：步进跟踪是1种常用于对地球同步卫星的跟踪方法,根据卫星轨道的稳定度设置相应的天线设备的跟踪参数。卫星在轨道上与理论位置存在相对位移,为了稳定跟踪,天线伺服设计时需要考虑跟踪速度,扫描范围,跟踪步距,重新捕获信号强度等,天线跟踪有步进跟踪,单脉冲跟踪,扫描跟踪等,其中步进跟踪成本低,易实现。步进跟踪实现稳定可靠的跟踪是卫星和地面站数据传输的关键所在。多元非线性回归根据信号强度信息及对星角度数据生成回归模型,提前预测修正误差,保证实时跟踪,实现可靠通信。Step tracking is a commonly used tracking method for geostationary satellites,setting the tracking parameters of the corresponding antenna equipment according to the stability of the satellite's orbit.Satellites in orbit and the theoretical position of the relative displacement,in order to stabilize tracking,antenna servo design needs to consider the tracking speed,scanning range,tracking stride,recapture signal strength,etc.,antenna tracking has step tracking,single pulse tracking,scan tracking,etc.,of which the step tracking cost is low.Stepping tracking to achieve stable and reliable tracking is the key to satellite and ground view data transmission.Multiple linear regression generates a tracking model based on signal strength information and star signal data,predicts and corrects errors in advance,ensures real-time tracking,and achieves reliable communication.
