受机械加工与安装水平的限制，磁通门传感器的三个分量相互之间无法保证绝对正交，由此会带来三分量磁测数据误差。本文通过建立一种三轴正交角度与磁总场误差关系模型，并对该模型进行正演模拟、反演分析及建立一种修正算法，达到推算三个分量不正交角度并修正的目的。实验表明，采用该方法对实际三分量磁通门传感器进行不正交度的测试与修正后，能够使其在测量总场时的误差减小到±10 nT，减小了测量时所带来的误差。

Magnetic flux-gate sensor is limited by the installation and process, its three-components can not be absolute orthogonal between each other, so as to bring with measurement errors for data. In order to solve this problem, a new relational model of the three-axis orthogonal angle and magnetic field error is established, simulated, analyzed inversely and to set up a correction algorithm at end. The experimental results showed that the measurement error of magnetic field is reduced to ±10 nT after using this method to test and calibrate the non-orthogonal degrees of the three-components magnetic flux-gate sensor, and the measurement error has been significantly reduced.
