Abstract This paper introduces the composition and functions of 4.2 m antenna servo subsystem,analyzes the phenomenon of frame losing and the problem of AGC voltage lower than normal when using automatic tracking for receiving.Through a series of tracking tests,the fault causes can be located accurately.Aiming at the faults,the solutions are put forward,effectively enhancing the reception quality of satellite images and obviously reducing the number of dropped frames and improving the business level.
