| 摘 要： | 研究了航空器目标跟踪中继卫星的星间天线指向实时监视问题.设计了星间天线指向监视计算模型,通过对航空器实时位置和中继卫星轨道的求解,得到了惯性系下的天线指向矢量,再通过坐标转换和矢量投影,得到了航空器星间天线理论指向角.通过将计算得到的理论指向角与遥测的天线框架角作差,得到了天线指向误差.在此基础上完成了天线指向实时监视系统设计,并进行了跟踪过程天线指向精度的事后统计分析.该天线指向实时监视系统利用航空器的遥测信息实现了跟踪过程中星间天线的指向角及指向角误差的实时确定,取得了良好的应用效果,有效地保证了数据中继任务中航天器用户目标对中继卫星跟踪的准确监视.

| Abstract: | The real-time monitoring system of IOLA(inner orbit linked antenna) of user aircraft tracking the TDRS(tracking and data relay satellite) was studied.The monitoring computation model of the IOLA of user aircraft was established.The pointing vector of IOLA in the inertial coordinate frame was calculated with the aircraft real-time position and the TDRS orbit.Then through the coordinate conversion and vector projection,the pointing angle of IOLA was calculated.The pointing angle error was acquired according t... |
