摘要：
In order to improve the autonomous navigation capability of spacecraft, an integrated navigation method using X-ray pulsar and Doppler is proposed. The Doppler navigation takes the Doppler radial velocity relative to Sun as measurement information, and this method can not obtain all state estimates. The pulsar navigation system is completely observable, but the filtering period is too long to provide continuous navigation information. Because the two methods are complementary to each other, a federated filter is utilized to fuse the information from the pulsar navigation and the Doppler navigation. Because both the state equation and the measurement equation of two methods are nonlinear, an UKF (Unscented Kalman Filter) is used as a local filter. The simulation results have demonstrated feasibility and accuracy of this navigation method. Compared with the pulsar navigation, the integrated navigation method can provide higher position estimation accuracy.
