摘要:
介绍了美国最近实施的火星着陆任务———“火星科学实验室”在巡航段的姿轨控制和导航系统、巡航 轨道控制的约束条件、控制策略设计和执行过程,并对巡航段导航、制导与控制相关经验进行了分析和总结,对于 我国即将展开的自主火星探测具有一定的参考价值。可以得到的启示包括:通过蒙特卡洛仿真制定详尽的轨道控 制策略,对非引力作用进行精确建模并标定,细化各种故障预案,选择合适的运载火箭入轨瞄准点,并增加海外测 控站。

Abstract:
The guidance,navigation and control system,the restrict condition of cruise trajectory,the control strategy design and its implementation process of the recent U.S. Mars landing mission,Mars Science Laboratory,are introduced.Then the experience of cruise navigation,guidance and control is analyzed and summarized.This paper has some reference to future Mars exploration mission of China.Some suggestions including establishing strict flight path control strategy by Monte Carlo method,studying non-gravitation effect,fining various fault scenario,choosing appropriate injection aim point,and increasing the space measurement and control station abroad.
