In order to improve the accuracy of measurement and shorten the confirmation periad and applying the star calibration technology, principle, method and program of the photo-electronic tracking system have been resea.

In this paper, for the advanced technology of satellite calibration, the principles and methods of satellite calibration are illuminated, simulated and validated; the error model of TT & C radar is given and the calculation flow of satellite calibration is set up.

A method of measuring manual VSAT receiving antenna gain by using the satellite beacon and high gain standard horn antenna is described in this paper.
