| 摘 要： | X射线脉冲星导航是一种新兴的天文导航方法, 该导航方法可靠、稳定, 不受近地空间的限制, 但在轨道机动过程中导航精度不高. 针对此问题提出了X射线脉冲星/SINS组合导航方法, 对该方法的应用效果进行了数值仿真分析. 结果表明, X射线脉冲星/SINS组合导航在轨道机动过程中具有较高的导航精度, 有效抑制了惯性导航误差随时间的漂移, 提高了X射线脉冲星导航方法的通用性, 为X射线脉冲星导航的工程应用奠定了理论基础.

| Abstract: | X-ray pulsars navigation is a new celestial navigation method, the principle of which is steady, credible and free from the limits of the near earth space. But its navigation precision is poor whyen it is used in orbital maneuver. For this problem, X-ray pulsars navigation/SINS integrated navigation system is proposed and testified by simulation in this paper. Results shows that the navigation precision of this new navigation system is preferable even during the orbital maneuver, and the drift of navigation error of SINS is well controlled. The new navigation system extends the application of X-ray pulsars navigation and lays a theory foundation to the engineering realization of X-ray pulsars navigation. |
