| 3. | In deep space exploration missions , autonomous navigation technology is very important , and in this paper , we do some research into the autonomous navigation schemes of encountering small celestial bodies . it is mainly described as the follows : firstly , by analyzing the orbit characteristics and task requirements in encounter , the simplified orbit dynamic model for the deep space probe is built up , and whether the corresponding model error that meets the demanding of autonomous navigation task is validated 在深空探测任务中,自主导航技术是十分重要的,本文对交会小行星的自主导航方法进行研究,主要内容包括:首先,分析交会小行星的轨道特性及任务需求,建立简化的深空探测器轨道动力学模型,并验证了简化模型的误差能否满足自主导航任务的需求。 |
