摘要
为了进一步研究深空探测任务中航天器成功登陆小行星的技术,提出光学自主导航技术是实现小行星登陆的关键技术:介绍了光学导航理论方法;并对探测器登陆小行星过程中的航天器状态估计算法进行了讨论。
In order to further study the technology of spacecraft successfully landing on asteroids for deep space exploration missions,the paper proposed that optical autonomous navigation should be the key technology to realize asteroid landing:the principle and methods of optical navigation were introduced;and the algorithm of spacecraft state estimation during spacecraft landing on asteroids was discussed.
