摘要: 天问一号火星探测器成功实现了我国首次火星表面软着陆,进入舱制导导航与控制系统(GNC系统)负责在火星进入下降着陆过程实施进入舱的姿态与轨道控制,确保进入舱安全着陆火星表面.介绍了执行天问一号火星EDL任务的GNC系统飞行阶段划分、系统组成、方案架构,以及针对火星EDL任务的特色设计,最后介绍了GNC系统在轨飞行结果.

关键词: 火星着陆, 制导导航与控制(GNC), 天问一号, 进入、下降与着陆(EDL)

Abstract: Tianwen 1 successfully achieved China’s first soft landing on the surface of Mars. The entry capsule GNC system is responsible for the attitude and orbit control during the EDL process of the entry capsule to ensure a safe landing on the surface of Mars. The flight phase division, system composition, scheme design and specific design for the EDL process of Tianwen 1 entry capsule GNC system are outlined in this paper. The actual flight results of the entry capsule GNC system during the EDL process are also provided.

Key words: Mars landing, guidance, navigation and control (GNC), Tianwen 1 Mars spacecraft, entry, descent and landing (EDL)
