摘　　要：为了消除小倾角同步轨道卫星对某卫星导航系统无人值守通信站站间卫通链路带来的不利影响,通信站小口径卫通天线采取自动跟踪技术,保证天线实时对准卫星。通信站以程序跟踪作为小口径天线的日常工作模式,基本可以满足自动化运行要求。为了提高桁架式卫通天线跟踪的可用性,以自跟踪技术作为辅助手段,提高在特殊条件下天线使用可用度。本文简要阐述了天线跟踪技术在无人值守通信站小口径卫通天线中的研究及应用。In order to eliminate the negative effect of the small angle synchronous satellite, unattended communication station take automatic tracking technology for small caliber Satcom antenna, make sure that the antenna is aligned in real time. The communication station takes program tracking as a daily working mode and this way can basically meet the requirements of automatic operation. In order to improve the availability of quilted jacket Satcom antenna tracking, we use the self tracking technique as a supplementary means to improve the antenna using availability under the special conditions. This paper briefly describes the research and application of the antenna tracking technology in the small caliber satellite communication station of unmanned communication station.
