利用月球引力场改变地球卫星轨道倾角原理

文章以休斯公司利用月球引力拯救“亚洲三号”通信卫 星的活动为背景，引入影响球的概念，对利用天体引力场改变航天器运行轨道倾角的原理进 行了探讨，并得到利用目标天体改变轨道倾角所应满足的两个条件：目标天体的运行轨道和 空间位置。利用一条假设的卫星轨道说明了月球引力场对其轨道倾角的影响。

The Theory of Changing Satellite Orbit Inclination Using Moon Gravitation

The activity of Hughes using moon gravitation for orbit change of “Asiasat-3” satellite made great sensation in the world.In this pap er,through the concept of effect sphere,explained the theory of orbit inclinatio n changing using gravitation of celestial body is explained.To use this theory,t he orbit and the space position of the celestial body must fulfil certain condit ions.A supposed orbit to show the effect of the moon gravitation on the orbit in clination is also introduced.
