摘　　要：随着天文观测技术的发展,一类在X射线频段发出辐射的脉冲星显示了良好的导航特质,由此发展了一种全新的基于X射线脉冲星的航天器自主导航方法。该方法通过探测X射线脉冲星发出的周期性脉冲信号进行导航,有别于传统的光学、射电天文导航。本文综述了基于X射线脉冲星自主导航技术,介绍其由来、发展历程、国内外研究现状,并对当前围绕该导航技术开展的研究工作进行了详细的分析,最后总结了需要进一步研究的若干问题。With the celestial observation developments, one kind of pulsars emitting the X-ray bands of the spectrum show good properties for navigation. It navigated by detecting the periodic signals emitted by pulsars, which is different form optical and radio celestial navigation. A survey of the X-ray source-based autonomous navigation technology is given in this paper. The origin of using pulsars for navigation and the history of the pulsars-based navigation are presented. The study situation at home and abroad on XNAV is described, and the current research on this navigation technology is analyzed in detail. Some problems for advanced research are summarized in the end.
