摘要: 嫦娥六号着陆上升制导导航与控制(guidance, navigation and control, GNC)系统圆满完成了月背着陆及自主月面起飞的飞行任务.本文系统总结了嫦娥六号着上GNC高可信飞控仿真与支持系统(以下简称飞控系统)设计.相比嫦娥五号飞控状态,嫦娥六号飞控任务主要有两方面特点:一是单机产品经历长时间贮存,飞行过程面临失效风险.在飞控过程中,设计了多敏感器比对的方法,重点监视单机产品的工作状态,确保单机产品满足飞控任务的使用要求.另一方面,嫦娥六号月背起飞首次采用全自主月面起飞的飞行流程,流程执行的效果直接决定了月背采样返回任务的成败.在飞控过程中,设计了基于星敏感器输出姿态比较的方法,重点关注月面自主起飞过程中,自主起飞工作流程的正确性及适应性.通过在轨数据验证了该飞控系统设计的有效性.嫦娥六号飞控系统设计可以为后续嫦娥系列任务的飞控实施提供参考.

Abstract: The mission of landing on the back of the moon and taking off from the surface of the moon was successfully completed by Chang’e-6  guidance, navigation and control (GNC) system for landing and ascending. The design of high reliability flight control system for Chang’e-6 GNC is systematically summarized in this paper. Compared 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 technological 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 takeoff attitude based the star sensors is designed to focus on the monitoring of autonomous takeoff procedure. At last, the validity of the design is verified through the onboard data.
