摘　　要：针对在高转速条件下载体姿态测量时,MEMS陀螺高过载和量程不足问题,难以实时获得载体实时飞行姿态,提出了磁阻传感器的精确标定与补偿方法,推导了磁阻传感器的误差模型,采用实验室开发的磁组件和荷兰姿态航向参考系统(MTi)分别在单轴和三轴转台上进行了半实物仿真试验。实验结果表明:所提方法可获得有效对载体滚转等姿态进行有效测量,姿态误差精度在5°以内,可以满足大动态载体姿态解算的精度要求。In view that it is difficult to obtain the fly-attitude real time because of the MEMS gyro＇ s high load and shortage of measure range when a object rolls in high speed. A method of calibration and compensation to the magnetometer was proposed. And so was the error model. A serious of experiments were implemented based on the single-axis platform and the three-axis platform with the labmagnetometer module and the MTi. The experimental results indicate that this method can obtain the fly-attitude effectively and the error of attitude angles is within 5°,which could satisfy the request of measuring object attitude in high dynamic environment.
