The feasibility of application of X-ray pulsar-based autonomous navigation （XNAV） to satellites in halo orbits is discussed . 6-D state equations and 6-D measurement equations based on XNAV are proposed and numerical simulations on XNAV and orbit control by low-thrust strategy are given. The result shows that satellites can be kept moving in halo orbits around the interior Sun-Earth libration point （L1） under conditions of the present measuring precision. Finally, the choice of the value of the parameters in the experiment is discussed.
