For X-ray pulsar navigation (XNAV) is a hot and prospective research subject  and the optical navigation using asteroids is practical in space engineering  we designed an autonomous navigation system using one X-ray detector and one navigation camera. The measurement models of the XNAV based on the time difference of arrival and the optical navigation based on the images of asteroids are presented. To enhance practicality  the X-ray pulsars and asteroids are observed by turns. The batch least square filter  used by Deep Space I  is adopted to estimate the system state. The numerical simulation results show that the integrated navigation is feasible on the interplanetary cruise orbit. Moreover  compared with the XNAV and the optical navigation  the integrated navigation system can provide higher navigation performance.   太阳帆航天器的轨道控制研究 期刊论文 深空探测研究, 2008, 期号: 2, 页码: 7-12 罗超; 郑建华 收藏  |  浏览/下载：9/0  |  提交时间：2014/04/30 太阳帆  轨道控制  太阳极轨
