摘　　要：磁罗盘在不同地磁场下使用的性能有差异,而常规手段只能对磁罗盘在实验室地磁场环境下的性能进行校准,所以其校准结果在实际使用中是有风险的。介绍一种磁罗盘空间特性校准装置,主要由地磁场复现系统和三轴无磁转台组成,地磁场复现系统可模拟地球上不同经纬度和不同离地高度的地磁场,配合作为角度标准器的三轴无磁转台,对磁罗盘在地球上不同地磁场下的性能进行校准,确保磁罗盘在不同空间使用时的量值准确可靠。It is found that the performance of magnetic compass is different under different geomagnetic field. The conventional means can only calibrate the performance of the magnetic compass in the local geomagnetic environment of the calibration laboratory,so the calibration results are risky in practical use. This paper introduces a magnetic compass spatial performance calibration device,mainly composed of geomagnetic field reappearance system and three axis non-magnetic revolving stage. The geomagnetic field reappearance system can simulate the geomagnetic field with different latitude and longitude and different height of the earth,and coordinate with the three axis nonmagnetic turntable,as the angle standard device,to calibrate the performance of the magnetic compass under the earth’s different geomagnetic field,to ensure that the value of the magnetic compass in different space is accurate and reliable.
