基于亥姆霍兹线圈产生均匀磁场的特性，绕制了三轴亥姆霍兹线圈，通过改变3组线圈通电电流大小，分别产生3个正交方向的磁场，模拟地磁场强度，为地磁导航系统的半实物仿真实验提供地磁场环境。同时，就地磁导航半实物仿真的需求，对地磁场模拟生成装置进行了可重复性和线性度验证实验、响应速度测量实验、均匀性验证实验和稳定性验证实验，并建立了装置的输入输出模型，验证了装置的各项指标符合实验室需求。

Based on the feature that Helmholtz coils can produce a uniform magnetic field,we made triaxial Helmholtz coils to generate magnetic fields with three orthogonal directions for simulating the geomagnetic field intensity by changing the importing electrical current of the three coils .This device could offer geomagnetic field environment for the hardware-in-the-loop simulation of geomagnetic navigation system .A lot of experiments were made to find whether this device is suitable for the need of simulation .These experiments included the tests on repeatability and linearity,and on response speed,uniformity and stability .The input/output model of the device was also established .These experiments proved that the indexes of the device can satisfy the needs of the laboratory .
