摘　　要：考虑到火星探测任务着陆过程动态变化大,稀薄大气环境下开伞会对探测器产生剧烈晃动,为此天问一号探测器研制了一套高动态着陆惯导系统,从硬件产品、使用时序到导航算法方面均进行了针对性设计,以适应着陆过程中的高动态环境。此外,为验证天问一号探测器高动态着陆惯导系统的性能,设计了模拟火星开伞工况的火箭弹高空开伞试验,结果表明该高动态着陆惯导系统的设计满足火星探测任务需求。Considering that the landing process of Mars exploration mission is high dynamic,especially the parachute opening in the thin atmosphere of Mars will cause violent shaking of the probe,the Tianwen-1 probe has developed a high dynamic landing inertial navigation system,including product design,timing analysis and navigation algorithms.In order to verify the performance of the Tianwen-1 probe high dynamic landing inertial navigation system,the upper air parachute opening test by a rocket is designed to simulate the parachute opening condition of Mars.The navigation results show that the design of the high dynamic landing inertial navigation system meets the requirements of the Mars exploration mission.
