X射线脉冲星能为行星际探测提供自主运营、高精度的导航服务。行星际探测过程中脉冲星并非随时可见，如何选择脉冲星关系到该导航方法的可行性。本文利用脉冲星、航天器及第三天体位置关系从几何角度研究脉冲星可见性问题，证明了在绝对定位导航中第三天体遮挡与干扰问题的解的等价性并给出了基于可见性的脉冲星优先选择准则；研究了X射线探测器姿态运动对脉冲星探测的影响，引入姿态转移矩阵解决了脉冲星实时可见性问题；研究了第三天体位置对两个航天器间通讯链路畅阻的影响，给出了基于X射线脉冲星的相对定位导航时机。有关可见性问题而建立的脉冲星选择准则，为行星际探测X射线脉冲星导航的工程应用提供了基础。

X-ray pulsar-based navigation as a complete independence and high precision navigation method could be used for interplanetary exploration. How to choose pulsars will ultimately decide its feasibility, because pulsars visibility is a problem. Firstly, the paper computed the angles among pulsars, space probes and celestial bodies to research the visibility ingeometry way, concluded a united pulsars visible solution for planets eclipse and the Sun jamming, and then built navigation pulsars choice priority criterion in the absolute localization. Secondly, state transition matrix was introduced to research real time visibility when space probe’s attitude moving disturbed detector pointing. Finally, the paper researched the situation of communication link affecting by celestial body location between two probes and concluded the feasibility time of using relative navigation. These researches on building navigation pulsars choice criterion in visibility will be a foundation of using X-ray pulsar-based navigation for interplanetary explore.
