【摘要】 对肇庆地磁台2019年MAG-01H(010B)型及TDJ2(E)型两套磁通门经纬仪产出的基线值观测数据,进行了定量分析。结果显示:两套仪器观测的基线值系统误差小,观测精度高,具有同等观测精度和一致的变化趋势;TDJ2(E)观测的H分量基线值受温度影响比MAG-01H(010B)的大;FGM 01型磁通门磁力仪Z分量传感器受温度影响较大,H分量受温度影响较小,D分量基本上不受温度的影响。更多还原

【Abstract】 The paper quantitatively analyzes the baseline value observation data produced by the two sets of fluxgate theodolites MAG-01H(010B) and TDJ2(E) at Zhaoqing Geomagnetic Station in 2019. The results show that the baseline values observed by the two sets of instruments have small systematic errors, high observation accuracy,and the same observation accuracy and consistent change trend;the baseline value of H component observed by TDJ2(E) is more affected by temperature than that of MAG-01H(010B); the Z component sensor of FGM 01 fluxgate magnetometer is more affected by temperature,H component is less affected by temperature,and D component basically not affected by temperature.更多还原
