Method and Strategy of the Moon-to-Earth Trajectory Midcourse Correction
摘要
Abstract
In order to target the reentry angle, the reentry height and the landing site location, a fixed landing site midcourse correction method based on the linear correction theory is developed for the moon-to-earth trajectory. Taking a moon-to-earth trajectory with the semi-ballistic reen- try for example, the relationship between the velocity increment and the midcourse correction op- portunity is researched. And the strategy with two midcourse corrections is validated by the Mont-Carlo simulation. The results suggest that the midcourse correction method and strategy in this paper can satisfy the reentry parameters and the landing site location requirements of the moon sampling return mission.关键词
