摘　　要：针对捷变型窄波束天线建链时间短、指向精度要求高的特点,通过建立星间天线指向误差模型,从理论上分析了卫星位置、姿态、天线安装等偏差因素对天线指向误差的影响。同时,采用STK软件对MEO卫星的天线指向误差进行仿真实验,实验结果与误差模型的理论预期一致。For the characteristics of rapid variant narrow beam antenna that connection time is short and accuracy requirement is very high,through the establishment of inter-satellite link antenna pointing error model,it is analyzed that the influence of deviation factors such as position of satellite,attitude and antenna installations to antenna pointing error. Meanwhile,STK software is used to simulate the pointing error of the MEO satellite. The experimental result is consistent with the theoretical expectations of the error model.
