提出了一种基于磁强计和陀螺的弹箭飞行姿态测试方法。利用地磁测量､陀螺测量和卡尔曼滤波器来解算姿态角的算法。设计一种基于地磁和陀螺的姿态测量系统,利用组合样机在三维无磁性转台上采集数据,分析和处理了实验数据,对卡尔曼滤波器进行了测试。结果表明:该算法可用于旋转飞行体的姿态测量。

A missile/rocket flight attitude test method based on magnetometer and gyroscope was proposed. This arithmetic adopts geomagnetic measurement, gyro measurement and Kalman filter for solving algorithm of attitude angle. An attitude measuring system based on geomagnetism and gyroscope was designed. Through data collection on three-dimensional non-magnetic rotating platform by the integrated prototype, the test data was analyzed and processed and the Kalman filter was tested. The algorithm can be used to detect attitude of high-load rotary flight body.
