摘　　要：本文根据卫星在同步轨道上摄动的规律,运用三角学方法分析了摄动对地面站天线指向精度的影响,并且给出了通过“APPLE-ⅡE”型微机计算的、不同口径的天线在C波段和K波段增益损失量的若干结果。Based on laws of the Satellite perturbation in geostationary or-bit, this paper analyzed the influence of perturbation on the pointing accu-racy of earth-station antenna by means of trigonometry. Some results ob-tained through model 'APPLE-ⅡE' microcomputer that the amount of an-tenna gain reduction in C band and K band with various diameter are alsoprovided.
