摘要:

X射线脉冲星导航(XNAV)技术作为一种新型的航天器自主导航技术,是目前深空探测巡航段最有潜力的自主导航技术之一。X射线脉冲星导航的概念提出于20世纪80年代,经过数十年的发展,该技术已逐渐从理论研究走向空间试验。介绍了近些年国内外完成的脉冲星导航空间试验,系统梳理和分析了当前脉冲星导航空间试验使用的信号处理方法、导航方法和X射线探测终端。根据国内外脉冲星导航空间试验的特点,总结了目前国内脉冲星导航试验在在轨解算和X射线探测终端方面的不足。最后,结合空间试验的现状及工程应用的实际需要,对未来脉冲星导航空间试验进行了展望。

Abstract:

As a new spacecraft autonomous navigation technology, X-ray pulsar-based Navigation (XNAV) is one of the most promising navigation technologies for deep space exploration. The concept of XNAV was proposed in the 1980 s. After decades of development, XNAV gradually moves from theoretical research to space experiments. This paper introduced the space experiments on pulsar navigation completed at home and abroad in recent years, analyzed the signal processing methods, navigation methods and the X-ray detectors used in XNAV space experiments, and summarized the shortcomings of China’s XNAV space experiments in terms of on-orbit calculation and X-ray detectors. Based on the current situation of space experiments and the practical needs of engineering applications, the future development needs of XNAV are discussed.

Key words: X-ray pulsar, pulsar-based navigation, space experiment, pulsar signal processing, X-ray detector
