The X-ray pulsar is a special celestial source which possesses of the lighthouse effect in space. And its unique, stable and predictable pulse can be utilized for satellite navigation and attitude determination. In this paper, the pulsar description is presented to explain the properties conducive to satellite navigation. With the pulse phases detected at the satellite and predicted at the initial reference location, the range measurements about the satellite can be generated. The Kalman filter technology is used to combine the satellite dynamics and the range measurements. The simulation is provided to demonstrate the expected performance of the satellite position and velocity determination using the observed phase message within the Kalman filter.
