The Development of the Algorithm of the Satellite Autonomous Navigation Using X-ray Pulsars
X-ray pulsars can provide stable periodic signals which are benefit for timing and navigation. The X-ray pulsars-based navigation(XNAV)determines the satellites position and velocity by using the pulse phases detected at the satellite and predicted by the pulse timing models. With the detected pulse phase,the range measurement along the line-of-sight to the pulsar is derived. And the satellite position can be calculated with respect to the inertial reference location of the Earth center. In this paper, the range measurements of the satellite are incorporated with dynamics by the extended Kalman filter to improve the navigation resolution for the Earth-orbiting satellite. Several examples of different types of orbit are provided to analyze the performance of the designed EKF algorithm based upon measurements of X-ray pulsars phase.
