Embodiment Construction
[0020] In order to measure the remanent magnetic moment of the satellite in the magnetic field of the geomagnetic environment, the equatorial plane of the satellite installed on the test turntable is used to measure the remanent magnetic moment of the satellite, starting from 0° and turning a certain angle counterclockwise to measure the remanent magnetic moment of the satellite until Return to the initial position. During the rotation process, the direction of the satellite's remanent magnetic moment changes continuously with the satellite's rotation; but the direction of the satellite's induced magnetic moment always points to the earth's magnetic field and does not change with the satellite's rotation. If the inhomogeneous distribution of soft magnetic materials in the satellite is ignored, this assumption is reasonable, and the magnitude of the magnetic induction moment component of the satellite is also constant. That is to say, the field value of the measurement point is...
