摘要

设计一套基于全球定位系统（GPS）载波相位测量的短基线姿态系统。给出了系统的硬件结构

研究了一种综合利用QR分解法与卫星基线几何分布的模糊度解算方法

同时

提出了一种非单位向量的四元数姿态解算方法。经过静态和动态实验证明该系统可行。在基线为0.36m的条件下

星历收集完成后在30 s内可以计算出姿态角、偏航角

计算精度可以达到0.5°。

Abstract

A GPS-based multi-baselines attitude determination system

which can be used for micro-satellite

is designed.The algorithm of multi-baselines attitude determination is studied.There are two steps in general.The one is to determine the integer ambiguity

and the other is to calculate the attitude matrix.The QR decomposition algorithm is used to establish the search space of integer ambiguity

while the QUSET algorithm is used to get the attitude matrix.The field tests are conducted and the results show that the performance of the system is good and on condition that baselines are 0.36 m

attitude angle may be computed in 30 s

computing accuracy of yaw angle may be 0.5 °.It can be used to determine the attitude of micro-satellite.
