摘　　要：无人值守站小口径卫通天线要求全天候24h和不间断、长期稳定地进行程序跟踪运行。在实际运行过程中,天线会因为机械磨损等因素致使跟踪精度先缓慢下降,精度下降趋势会越来越快。如何实现小口径卫通天线长期稳定跟踪运行,是在实际工程应用中亟待解决的问题。The requirement of unattended station small caliber satcom antenna is the all-weather and long-term reliable running. In the process of actual operation, the tracking precision of antenna will be slow down because of mechanical wear, and the precision decline will be more and more quickly. How to realize a long-term stable running of small caliber satcom is the problem to be solved in the practical application.
