Embodiment Construction
[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0022] As shown in the figure, this vector (three-component) magnetometer calibration device is made of completely non-magnetic polyethylene material, and the parts are fixed by non-magnetic titanium alloy screws to ensure that the magnetometer is in the calibration experiment. It will not be disturbed by its own magnetic field. It mainly includes a vector magnetometer 4, a base 17, an outer ring rotating device, a middle ring rotating device and an inner ring rotating device, wherein the vector magnetometer 4 is fixed in the center of the inner ring rotating device, and the outer ring rotating device, the middle ring rotating device and the The inner ring rotates the device to change the attitude of the vector magnetometer 4, and the overall schematic diagram of the vector magnetometer calibration device is as follows figure 2 As shown, wherein the magneto...
