姿态测量系统是火箭弹简易制导领域不可或缺的一部分。文中基于地磁传感器与MEMS陀螺仪的姿态测量系统，对传统单点姿态测量方法进行了研究与改进。以MEMS陀螺仪解算所得的偏航角作为三轴地磁传感器输入，推导了姿态角测量方法。针对姿态测量方法，设计了三轴地磁传感器姿态测量模块，在三轴旋转平台上进行了半实物仿真实验。实验结果表明，改进后的方法可以满足火箭弹姿态解算，提高了姿态角解算精度。%Attitude measurement system is an indispensable part of rocket simple guidance field .Based on magnetometer and MEMS gyro-scope , traditional single-point attitude measuring method was studied and improved .Yaw angle solved by MEMS gyroscope was taken as in-put of three-axis magnetometer for measuring attitude angle .In view of the attitude measurement method , a three-axis magnetometer meas-uring system was designed and semi-physical simulation experiments were carried out on three-axis rotation platform .The results show that the improved method can satisfy missile attitude algorithm and the precision is improved .
