摘　　要：近年来商业航天发展迅速,中继卫星(Tracking and Delay Relay Satellites,TDRS)凭借其成本低、可快速部署等优势,已成为商业航天火箭发射测控系统的重要组成部分,且已多次应用于火箭发射。以TDRS支持航天发射为具体应用场景,研究卫星天线指向火箭和箭载终端天线指向卫星的算法模型,基于Matlab将算法进行可视化实现。所提指向算法可以根据TDRS定点位置和火箭发射参数,计算TDRS和火箭天线指向结果,快速获取测控任务双向可视弧段,缩短TDRS支持航天发射测控任务响应时间。Commercial space business has developed rapidly in recent years.Tracking and Delay Relay Satellites(TDRS)have been applied many times in rocket launches and become an important part in the commercial space rocket launch tracking telemetry and command system with its low cost and rapid deployment advantages.Using TDRS to support space launch as a specific application scenario,the antenna pointing algorithm model of satellite to rocket and rocket terminal to satellite has been studied,and the algorithm visualization is implemented based on Matlab.The proposed pointing algorithm can calculate the pointing results of TDRS and rocket antenna based on the fixed point position of TDRS and rocket launching parameters,quickly obtain bidirectional visual arcs for the TT&C tasks,and shorten the respond time of TDRS supporting space launch TT&C tasks.
