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.   Doppler/XNAV-integrated navigation system using small-area X-ray sensor. 期刊论文 IET Radar, Sonar and Navigation, 2011, 卷号: Vol.5 No.9, 页码: 1010-1017 作者:  Jing, L;  Zhi-wei, K;  Paul, W;  Jie, M;  Jin-wen, T 收藏  |  浏览/下载：3/0  |  提交时间：2020/01/05 Doppler-XNAV-integrated navigation system  small-area X-ray sensor  X-ray pulsar-based navigation  radial velocity  measurement equation  nonlinear equation  UKF  unscented Kalman filter  federated filter
