火星科学实验室着陆系统全过程GNC技术分析

Analysis of GNC Technology in the Whole Process of Landing System of Mars Science Laboratory

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 classic Mars exploration mission,using the example of Mars Science Laboratory of America,the paper deeply analyzes and researches the Guidance,Navigation and Control(GNC)system of the whole process,and states the key technology systematically.Based on the current technology and development trend,it sumarizes the status of landing scheme of typical detectors,and puts forward prospect for the landing phase of future Mars exploration.The outcomes of this study can serve the design and demonstration of planetery exploration scheme in China.
