Abstract

X-ray pulsar-based navigation is a novel autonomous navigation method. The pulsar is a kind of neutron star rotating with high speed. Its angle position is stationary in space and its rotation period is extremely stable. In space, the signal with extremely stable period could be detected. Its long-term stability is higher than the atomic clock in state-of-the-art. Therefore, the signal of the pulsars in X-ray waveband could be used for the autonomous navigation of the spacecrafts. The signal’s profile is a necessary parameter to estimate the navigation information. In this paper, the impact on the navigation precision caused by the flux bias of the signal’s profile is analyzed. The impact is not severely proved in theory and simulation.
