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.   Imaging performance analysis for the Geostationary Interferometric Microwave Sounder (GIMS) demonstrator 会议论文 2012 12th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment, MicroRad 2012, Rome, Italy, March 5, 2012 - March 9, 2012 作者:  Zhang, Cheng;  Liu, Hao;  Wu, Ji;  Zhang, Shengwei;  Yan, Jingye 收藏  |  浏览/下载：51/0  |  提交时间：2014/12/15 Finite element analysis of lightweight, active primary mirror 会议论文 Proceedings of SPIE: 6th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Large Mirrors and Telescopes, 2012 作者:  Lu, Wei Xin;  Guan, Chun Lin;  Rao, Chang Hui 收藏  |  浏览/下载：8/0  |  提交时间：2016/11/24
