摘　　要：为了能够不依赖外部基准实现对地磁场测量系统误差的补偿,提出了基于最小二乘法的地磁场测量误差补偿方法。实验表明,对地磁测量系统的输出数据进行校正效果明显,补偿之后系统的均方根误差由4267nT减小到224nT,补偿方法能够快速方便地消除地磁场测量系统的误差。To correct errors of the measurement system of geomagnetic field without the help of external refer- ence, established an error model for independent solving, proposed an error correction method based on least squares method. Results showed that after error correction the root mean square error of the system was de- creased from 4267nT to 224nT. The correction method could quickly and conveniently eliminate errors of meas urement system.
