Recovering pulse template is one key technology of X-ray pulsar-based navigation system. Its precision is closely related to the pulsar angular position. First, this paper briefly introduced the theory of recovering standard profile. Then, the impact of pulsar angular position error on pulse template was analyzed and its analytical formula of annual mean value and the integral for any arc segment were derived. Finally, we proposed a feasible way that can significantly decrease the impact of pulsar angular position error. These research conclusions and simulation analysis verify the effectiveness of error compensation method, which could provide reference for optimizing observation task of X-ray pulsars and recovering X-ray pulse template.
