现代天文导航及其关键技术

Modern Celestial Navigation and the Key Techniques

分析导航技术的地位、作用及其局限性,综述天文导航技术现状及国内外对天文导航技术的认识,指出天文导航技术的优点,在此基础上,重点论述天文导航关键技术,提出基于自然天体及人造天体射电测量、消除水平基准制约和可见光观测限制的天文导航技术发展思路.

The status,function and limitation of current navigation techniques are analyzed,the current technologic condition and anderstandings to celestial navigation techniques are summarized, the advantages of celestial navigation techniques are pointed out. Based on this, the emphasis of this paper is to discuss some key techniques in improving celestial navigation, such as the radio signal measurement of both natural and artificial celestial bodies, some new celestial navigation methods which are free from horizontal benchmark or visible light observation.
