摘要
针对陀螺作为惯性测量系统测量飞行体姿态的重要器件存在零点漂移误差的问题,本文提出使用地磁线圈测量飞行体的旋转角速度,根据磁线圈输出信号的特征点或变化周期对陀螺测得的信号进行修正。详述了利用线圈的磁通量变化测量飞行体飞行姿态的原理,并由法拉第电磁感应定律推导出飞行体旋转角速度的计算公式。
Aiming at the gyro, which is an important component of inertial measuring unit, exist drift error . This paper advances using geomagnetic induction coil to measure the attitude of flight body. Based on the output of coil, like the characteristic order or the period variety, to revise the output signal of gyro. According to Faraday electromagnetism induction law,we deduce the attitude measurement method of flight body.
