摘要
本文提出了一种用于卫星导航系统站间卫星通信的天线跟踪与自校准方法,该方法利用卫星导航电文信息计算出卫星准确的方位角和俯仰角用于天线跟踪,相比传统的天线步进跟踪方法,不会出现跟踪失败的情况,提高了天线跟踪的可靠性,并在进行天线跟踪的同时,完成了天线指向的自校准工作,减少了人工维护工作量。
An antenna tracking and self-calibration method for stations satellite communication in satellite navigation system is proposed in this paper. Accurate azimuth angle and pitch angle of the communication satellite which are calculated with satellite navigation message are used for antenna tracking. Compared to traditional antenna step tracking method, this method has a higher reliability and the tracking failure does not occur. Moreover, maintenance work decreases because the antenna self-calibration is completed while antenna tracking.
