嫦娥六号着上GNC高可信飞控系统设计及验证
Design and Verification of High Reliability Flight Control System for Chang'e-6 Lander and Ascender GNC
摘要
Abstract
The mission of landing on the back of the moon and taking off from the surface of the moon was success-fully completed by Chang'e-6 guidance,navigation and control(GNC)system for landing and ascending.The de-sign of high reliability flight control system for Chang'e-6 GNC is systematically summarized in this paper.Com-pared with Chang'e-5,there are two main features.One is that all the hardware products experience a long period of storage and have failure risk.So for Chang'e-6 flight control system,the method of multi-sensor comparison is designed and the focus is to monitor the work status of all the hardware products in order to make sure that all the hardware products meet the operating requirements.The other is that Chang'e-6 firstly adopts autonomous techno-logical process during taking off from the surface of the moon,which has great impact on the lunar sample return mission.So a method of calculating take-off attitude based the star sensors is designed to focus on the monitoring of autonomous take-off procedure.At last,the validity of the design is verified through the onboard data.关键词
