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.
