摘要
为了确保琼中台FGM-01磁通门磁力仪观测数据的准确性,对琼中台多套地磁相对记录仪分钟数据作相关系数分析,及对其观测基线值作月剩余标准差处理和日均差值对比分析,分析结果得出FGM-01仪的观测精度及稳定性较差。
In order to ensure the observation data accuracy of FGM-01 fluxgate magnetometer at Qiongzhong Station,this paper makes correlation coefficient analysis for minute data of several sets of geomagnetic relative recorders at Qiongzhong Station,and makes monthly residual standard deviation processing and comparative analysis of daily mean deviation for their observed baseline values.The results show that the observation accuracy and stability of FGM-01 magnetometer are poor.
