摘要
分析了利用射电星校准13m测控天线指向精度的方法,综合利用射电星和光标测试数据,采用简化的天线误差模型,计算出天线误差系数,经过误差修正后天线的指向精度达到设计要求。
The means using radio star to calibrate 13 m TT&C antenna pointing errors is analyzed.The antenna error coefficients are obtained jointly using the radio star and optical target test data according to a simplified antenna error model.The antenna pointing accuracy satisfies the design requirements after errors are corrected.
