Fig. 15From: First in-orbit results of the vector magnetic field measurement of the High Precision Magnetometer onboard the China Seismo-Electromagnetic SatelliteThe magnetic field disturbances on FGM measurements. a The magnetic field disturbances on FGM2 z component when the magnetic torque operates. Nine data series are shown. The magnetic torquer utilizes the time pulse-width modulation mode, so the interference strengths match well every times it works. b The residues under different magnetization directions vary. With the ground calibration data, this difference can be accurately eliminatedBack to article page
