| 摘 要： | "嫦娥三号"探测器首次实现了我国航天器在地外天体软着陆,制导导航与控制技术是软着陆任务成功的关键。针对高安全和高可靠软着陆任务的要求,设计了包含接力避障的软着陆飞行程序,提出了单波束分时修正与多波束融合修正的自主导航方法和自适应动力显式制导、无迭代多项式粗避障制导以及内外环结合的精避障制导等方法。实际在轨飞行结果表明,导航算法提供了高精度的状态估计,制导算法实现了高精度状态控制和有效避障机动,确保了软着陆落月的安全性和可靠性。

| Abstract: | Chang'' e-3 implemented its soft landing on the moon which is the first time for a Chinese spacecraft to conduct soft landing on an extraterrestrial body. GNC is the key to achieve successful soft landing. For the desire of high safe and reliable soft landing, the soft landing flight program including rough-fine-relay hazard avoidance is designed, the autonomous navigation method based on single beam time-sharing correction and multi-beams fusion filter, and the self-adaption powered explicit guidance, the non-iteration polynomial large hazard avoidance guidance, the inner-outer-loop small hazard avoidance guidance are presented. The real flight result of Chang'' e-3 shows integration that the high-precision states is estimated by navigation algorithm, the high-precision states control and effective hazard avoidance maneuver areimplemented by guidance algorithm to ensure the safety and reliability for lunar soft landing. |
