摘　　要：X射线脉冲星导航系统是“天然的GPS”导航定位系统，能够为近地轨道、高轨道对地摄影测量卫星和环绕其它行星的摄影测量卫星提供卫星的位置、速度、姿态、时间等定位、定姿数据，满足无地面控制的航天摄影测量数据处理的需要。本文初步探讨了X射线脉冲星导航定位系统在航天摄影测量中应用的主要技术问题，包括：摄影测量卫星脉冲星导航数据获取、脉冲星导航数据处理和脉冲星导航数据与摄影测量数据联合平差等问题。Navigation system based on X - ray pulsars is a ＂natural GPS＂. It can provide position , velocity , attitude and time information for the photogrammetric satellites at the low earth orbit, the high earth orbit and orbiting other planets. These information can meet needs for photogrammetric data processing without the ground control points. This paper investigates the main technology on the application of X - ray pulsars navigation system to space photo- grammetry. These technologies include navigation data acquirement for photogrammetfic satellite, navigation data pro- cessing and combining bundle block adjustment with X - ray pulsars navigation inrormation and photogrammetric data.
