| Abstract: | GM4 fluxgate magnetometer is the main equipment of geomagnetism in the ＂Tenth-five year project＂,the interferences to which are mostly of iron magnetic material and electromagnetic types.According to the given interference types,distortion of observation data is contrasted,analyzed and summarized so as to distinguish and preprocess interferences appropriately,keep the observation as consistent,reliable and accurate as possible. |
