摘要
本文阐述了利用X射线脉冲星实现航天器姿态确定的成像仪定姿、探测器扫描定姿和垂直双矢量相对定位姿态的3种方法,介绍了其基本原理;分析了3类方法与现有姿态确定方法相比存在的优势;并利用仿真数据分析了垂直双矢量相对定位姿态确定方法;研究了时延测定误差、可观测脉冲星数、脉冲星历表误差等对姿态确定精度的影响,得出了有益的结论。
Three kinds of X-ray pulsar attitude determination methods were presented in this paper. First, the basic principle of this method was introduced, and their advantages were compared with existing methods. Then, the vertical pair vector relative attitude determination methods were tested using simulated data. Focusing on the attitude determination accuracy, the impact of the time delay measurement error, the number of observable pulsars and the pulse＇ s ephemeris error were studied, and some useful conclusions were given finally.
