摘　　要：针对弹体高速旋转下一个微机械陀螺和磁传感器组合无法测量弹丸姿态角的问题,用磁传感器和微机械陀螺构建了新型低成本姿态探测系统。该系统由两个微机械陀螺和一个三轴磁传感器组成,通过测量弹体三轴磁场强度、双轴角速度,实现姿态探测。计算机仿真分析表明:该姿态测量系统可以准确地捕捉到弹体姿态角,实现高速旋转下弹体的姿态测量。Aiming at the problem that the combining of MEMS-gyro and three-axis-magnetometer can＇t achieve shell＇s attitude detection on high rotating speed,a low cost attitude detecting system composed of geomagnetic sensor and MEMS-gyro was proposed.The system consisted of a three-axis-magnetometer and two MEMS-gyros,andf detected shell＇s attitude by measuring magnetic field intensity and angular rates.Simulation results showed that the proposed algorithms were demonstrated to be successful in determining a accurate attitude under the condition of high rotating speed.
