In ground segment of aircraft TT&C system,the time delay of some antenna systems can not be calibrated accurately by beacon tower. For this shortcoming,a calibration method is proposed in which an-tenna system is computed and measured segmentally. The calibration accuracy is analyzed and computed. The effect of different factor on the time delay variation of antenna system is analyzed. Engineering practices prove the feasibility of the proposed method. The calibration accuracy is better than 0. 1 ns.
