X脉冲星矢量多平面观测的姿态测量

目的：本文提出一种基于X射线脉冲星矢量多平面观测的姿态测量方法，方法：脉冲星矢量观测采用若干个具有不同方向的平面组成一个立体结构、并在每个平面上安装脉冲星传感器，通过测量在不同平面内接收的X射线脉冲星光子功率，以及功率的测量值和各平面之间的相对几何关系，可以计算出脉冲星的矢幅值和空间角，结论：实现了X射线脉冲星矢量的测量。目前基于以上方法已经完成仿真实验验证。结论：X脉冲星姿态多平面测量方法能够为今后的航天器应用提供较高的姿态测量精度，有利于今后航天器的发展。

Study on Attitude Measurement Based on Multiple Plane X-Ray Pulsars Vectors Observation

Objetive: This paper describes the design, tests and preliminary results of a multiple-plane sensor detecting the X-ray pulsars vectors to acquire the spacecraft attitude. Method：Comparing to the star sensors or other traditional attitude measuring, the multiple-plane sensor has made an adversary and new effort by inventing a multiple-plane structure, with the orthogonal vectors pointing towards the different directions. By measuring the power received by each plane and considering the geometry relationship of the planes, the sensor computes the pulsars vector from a certain pulsar. Result： the attitude of the spacecraft can be acquired if vectors from several different pulsars is recognized and specified. Conclusion：Accordingly the simulation is established and the result proves its charming feasibility in future spacecraft missions.
