摘　　要：地磁导航由于受载体自身磁场的干扰,严重影响了其导航定位的精度,其中飞行器干扰磁场中恒磁磁场以及激磁磁场对地磁场测量的影响最大。利用积分方程法理论,推导了载体运行时三轴磁传感器测量值的组成,建立了误差补偿模型,明确了模型中所含测量参数的物理意义,实现了对飞行器磁场的精确补偿,解除了飞行器磁场误差补偿过程中要求在水平面内运动的限制。最后利用实验数据进行验证,该模型能较好的满足导航定位要求。Magnetic navigation due to interference by the carrier's own magnetic field,the accuracy of navigation is seriously affected,the constant magnetic field and excitation magnetic field affect the measurement of the magnetic field.Using integral equa⁃tion theory,the measurements of the three-axis magnetic sensor are derived,the error compensation model is established,the physi⁃cal significance of measurement parameters in the model is defined,the precise compensation of aircraft magnetic field is realized,the limitation of the plane motion in the compensation of aircraft magnetic field error is removed.At last,the experimental data are used to verify that the model can meet the navigation require.
