摘　　要：大型深空测控天线需要利用射电星进行标校,同时为了提高深空测控精度,也需要利用射电星进行VLBI测量,射电星的观测位置是进行标校和VLBI测量的基础。通过时间系统和空间坐标系,利用地球参数进行坐标转换,得到射电星在地平坐标系的极坐标位置,并将计算过程结合到天线控制系统中,有利于实现大型深空测控天线的VLBI测量。Large deep space measurement and control antennas need to be calibrated by radio stars,at the same time to improve the accuracy of deep space measurement and control,VLBI measurement are also required using radio stars,Radio star observation is the basis of calibration and VLBI measurement.Through the time system and spatial coordinate system,coordinate conversion using earth parameters,get the polar position of the radio star in the coordinate system,the calculation process is integrated into the antenna control system,it is helpful to realize VLBI of large deep space measurement and control antenna.
