Abstract In order to select the optimal pulsars combination for X-ray Pulsar NAVigation (XPNAV), the influence factors of visibility, quality and space distribution of pulsars are studied. Besides, constraint equations for visibility based on the restrictions of celestial body’s shadow, X-ray disturbance source and detector’s angle of view are built respectively; an evaluation equation for quality factor based on Cramer-Rao low bound is analyzed; the method for calculating Weighted Dilution Of Precision (WDOP), which decreases as the number of observable pulsars increases, is researched. Finally, a method for selecting pulsars based on looking up table is proposed, and its validity is proved by computer simulations.
