基于经典火星探测任务的数据对比,以美国最近实施的火星着陆探测器“火星科学实验室”为例,对着陆全过程的导航、制导与控制(Guidance Navigation Control,GNC)系统情况进行了深入的分析和研究,对其中的关键技术进行了系统阐述。基于目前技术和发展方向,总结了典型的探测器着陆方式的研究现状,并对未来火星探测着陆段提出展望。可为中国火星以及其他行星的探测任务方案的设计与论证提供参考。
Based on the data comparison of the classical Mars exploration mission, taking the Mars Landing Probe “Mars Science Laboratory” recently implemented in the United States as an example, the situation of the Guidance Navigation Control (GNC) In-depth analysis and research, the key technologies of which were systematically elaborated. Based on the current technology and development direction, the research status of the typical detector landing pattern is summarized, and the prospect of the Mars exploration landing segment in the future is put forward. It can provide reference for the design and demonstration of the exploration missions of Mars and other planets in China.
