| 摘 要： | 本文以轨道摄动分析方法一阶理论为基础，其中大气阻力摄动采用数值积分方法，给出一种可利用各种大气模型进行轨道摄动分析的计算方法，并利用三种高层大气模型（ＣＩＲＡ—７２，ＣＩＲＡ—８６和ＤＴＭ）和三个太阳活动水平（Ｆ１０．７＝１００，１５０和２００）分析比较了大气阻力振动对高度为４００ｋｍ的空间站轨道漂移和寿命的影响，以及估算修正轨道漂移所需的能量。给出的定量分析结果将为空间站或航天飞行器的轨道设计和能量估算提供依据。

| Abstract: | Based on an analytic theory of orbital perturbation this paper describes a calculated method in which the atmospheric drag perturbation is calculated by using numerical intergration. The atmospheric drag effects on the orbital drift and lifetime of the space station at the height of 400 km were analysed by using this method for three kinds of upper atmospheric models (CIRA - 72, CIRA-86 and DTM) and three solar activity levels (F10. 7=100,150 and 200).The energy required to correct orbital drift was estimated.The quantitative results given by this paper are useful for the design of the orbit of space station or a platform and the estimation of required energy. |
