摘　　要：地磁导航作为一种无源、自主、无辐射、全天时的导航方法,越来越受到学者的关注。利用加权余量原理,针对内部包含永磁体、软磁铁、通电导线的运动载体建立矩阵方程,并进行运动和电磁场的耦合;应用有限元法计算运动载体在变化的外加磁场下的磁场分布,在空间上取离散点进行磁场数据的采集并建立地磁导航数据库,与载体内部磁场值对比,得出运动载体的空间位置,给出实现地磁导航的方法。As a passive,autonomic,radiation-free,round-clock way of navigation method,geomagnetic navigation techonlogy are becoming more and more noticeable among scholars.In order to better apply the geomagnetic navigation technology,it is necessary to build a model that can determine the changing position of the motion carrier according to the variation of magnetic field at different points.Using the weighted residual principle,the motion vector contains internal permanent magnet,magnetic,electrical wire of a matrix equation,and motion and electromagnetic coupling.The application of finite element method illustrates the motion vectors in the magnetic field distribution during magnetic field changes.Taking several points in space to build the discrete geomagnetic navigation database,it shows the geomagnetic navigation method.
