An X-ray pulsar-assisted autonomous celestial navigation method for Earth-Mars transfer stage is designed. The pulsar differential measurement model is deduced to suppress the systematic error of pulsar navigation method. Two-level information fusion algorithm is proposed as well, where the main filter performs time-update and solar/planetary measurement update, the auxiliary filter adds the pulsar measurement to correct the navigation information precision further. The proposed fusion algorithm can solve the inconsistent measurement update frequency between solar planetary measurement and pulsar measurement. Simulation results show that the proposed method can improve the position and velocity accuracy compared with the traditional integrated navigation method.
