摘要
嫦娥一号卫星航天使命的主要科学目标是对月球及月地空间进行多种遥感探测,航天使命设计的主要和基本的部分是卫星飞行轨道的设计,其中包括在飞行过程中的轨道控制策略的设计。嫦娥一号的这条飞行轨道由三大部分组成:第一部分是绕地飞行的调相轨道,它们由周期为16h、24h、48h的三段轨道组成;第二部分是关键的地月转移轨道;第三部分是200km高度绕月飞行的使命轨道。文章给出了整个飞行轨道的设计思想。
CE-1 is the first Chinese probe to explore the Moon. The main scientific objectives of this mission are remote sensing of the moon and the cislunar environment investigations. The primary and basic part of the mission design is the orbit design of whole flight process, including the orbit control strategy. The flight consists of three segments. The first is phasing orbits segment which includes three orbits with periods of 16,24 and 48 hours; The second is translunar-trajectory being key part of the flight. The last segment is a mission orbit which is circular one with altitude of 200km and inclination of 90 degree to lunar equator.
