针对如何解算弹体在地磁场中旋转姿态这一问题,利用地磁场特性原理,提出了采用地磁传感器和光电传感器相结合的方法解算弹体的滚转姿态信息,分析对比了基于单轴与三轴地磁传感器的弹体滚转角的实时解算方法,通过三轴地磁传感器解算方法对弹体进行旋转位置标定实验,测量结果表明:基于地磁传感器解算方法可以实现对弹体滚转姿态的实时解算,解算角度误差在4°以内。

Aiming at solving the problem of rotating attitude of the projectile in the earth’s magnetic field,a method combining geomagnetic sensor and photoelectric sensor was proposed to solve the rolling attitude information of the projectile,using the principle of geomagnetic field characteristics.The real-time solution method of the body roll angle of the single-axis and three-axis geomagnetic sensors was carried out by the three-axis geomagnetic sensor solution method.The results show that the geomagnetic sensor solution can be realized.The real-time solution of the rolling attitude of the projectile,and the solution angle error is within the reasonable experimental range.
