| Abstract: | The domestic fluxgate magnetometers (the GM-3 fluxgate magnetometer) have been applied in all geomagnetism stations in our country for more than two years. In the last two years, the digital work more stabilizing. In this paper, the baseline data of this digital record are analyzed with regression analysis. And we also analyze the hourly means, the daily means, the monthly means and yearly means by contrast among the GM-3 fluxgate magnetometer, the other digital terrestrial magnetism recorders and the simulate terrestrial magnetism records. By the analyzing result, it is easy to say that the domestic fluxgate magnetometer works more stability. |
