摘　　要：安装在铁磁性的测量载体上的地磁场三分量测量系统,由于受到载体磁化磁场的干扰,给地磁场的解算带来了极大的困难。针对船载地磁场三分量动态测量系统,阐明了地磁场的解算原理,指出了其中的难点问题。对地磁场三分量的动态解算方法进行了实验室模拟,结果表明地磁场三分量航海测量具有实施的可行性。The computation of three-component geomagnetic field with onboard geomagnetic measurement system is difficult for the interference of vessel＇ s magnetization field. The principle of obtaining geomagnetic field is explained, and difficult point are presented. The dynamic computation of three-component geomagnetic field is realized in laboratory. The experimental results show the feasibility of marine measurement of three-component magnetic field.
