三轴磁强计已被广泛应用于空间磁场的测量。分析三轴不正交对三轴磁强计测量结果带来的影响，得到三轴磁强计的误差校正公式，建立求解非正交误差角的最优化数学模型，并运用自适应遗传算法对模型进行求解，实现对磁强计固有参数的辨识和测量误差的校正。通过FGM-2000三轴磁力仪实测实验对校正方法进行验证，结果表明，校正方法效果明显，仪器的测量误差减小了88.1%，测量精度显著提高。

Tri-axial magnetometers are widely studied and used in geomagnetic measurement. The influence on the measurement results caused by tri-axial nonorthogonality is analyzed,and the calibration formula is established. An optimization mathematical model is established to get the nonorthogonal error angles, and the Adaptive Genetic Algorithm is used to solve the model,in order to achieve the identification of intrinsic parameters and the calibration of measurement errors. The measurement experiment of FGM-2000 tri-axial magnetometer is done to verify the calibration method,and results show that the effect is obvious,the measurement error is reduced 88. 1% and the measurement accuracy is significantly improved.
