摘要
为了计算登月飞行轨道，需要知道摄动力对登月飞行轨道的影响，以便计入满足精度要求的所有摄动模型。与人造地球卫星轨道相比，登月飞行轨道有一些不同的特征，这些特征使得登月飞行轨道所受的摄动力的影响不同于人造地球卫星所受的摄动影响。我们采用适当的方法选取了满足登月飞行轨道计算精度要求的摄动模型。
In this paper, perturbations' influences on lunar - landing orbit are studied. Because of some of the lunar - landing orbitjs distinguished features which are not owned by an artificial earth satellite orbit, the perturbations' influences on lunar - landing orbit are different from those on the artificial earth satellite orbit- So the usual method for estimating perturbation influence on an artificial earth satellite orbit determination is not valid any longer for lunarlanding orbit. We explain the reason and devise a new method for choosing appropriate pertubation models to satisfy the precision requirement of lunar - landing orbit determination.
