脉冲星具有自转非常稳定的特性,在空间自主导航中有重要的应用前景.选择和研究一组适合于脉冲星导航使用的候选目标源非常重要,决定脉冲星导航精度的主要因素有:导航目标源X射线流量强度、目标源的位置精度和旋转参数精度.对可用于导航的一些X射线源进行了讨论研究,并对最适合做导航研究的转动能驱动的X射线脉冲星进行统计分析.%Pulsars have very high rotational stability, which allow them to be applied for autonomous navigation in space. Selecting a set of X-ray pulsar sources for autonomous navigation is a very important work. X-ray pulsar flux density, position and rotational parameter precision are very important to navigation. This paper describes the assembled X-ray pulsar navigation sources catalogue in detail, X-ray pulsar can be grouped in three different families according to the powering source: accretion-powered pulsars(APSRs), rotation-powered pulsars(RPSRs) and anomalous X-ray pulsars(AXPs). By analyzing their characteristics, APSRs and AXPs are not suitable candidates. RPSRs possess the most advantageous characteristics for navigation. We gather all RPSRs into one collective set. Totally, 34 RPSRs have been detected with the X-ray pulse profiles, including 10 millisecond pulsars, which could form the basis of navigation system. In addition, 32 other sources have only been detected with X-ray radiation, which may need high sensitivity X-ray detector to detect the pulse profiles. Then, we provide briefly discussion on the RPSRs, including their properties at radio and X-ray band, which allows the analysis of each source for its potential as a candidate for navigation purpose. Finally, we present a set of pulsars which may be suitable for China X-ray navigation experiment in the future.
