Abstract

The invention provides a system and method for eliminating the residual magnetic interference of a micro-satellite. The residual magnetism of a micro-satellite platform is modeled as a magnetic dipole, vector magnetometer probes are separately arranged at the tail ends of two symmetrical extending rods on the satellite surface, the internal relation between magnetic field gradient integral and magnetic field values is used for estimating the residual magnetic interference of the satellite platform, and geomagnetic field values at the position of a satellite body is given. The system and methodfor eliminating the residual magnetic interference of the micro-satellite use the method of the magnetic field gradient integral to present a satellite platform residual magnetism estimation method,and the purposes that the satellite platform residual magnetic interference can be eliminated and the accuracy of spatial geomagnetic field measurement is improved are achieved.

Description

Technical field [0001] The invention belongs to the field of geophysical satellite magnetic exploration, and relates to a system and method for eliminating magnetic interference of a micro-satellite platform based on magnetic field gradient measurement. Background technique [0002] Satellite magnetic survey, as an important geomagnetic field detection method, has been widely used in the field of geophysical satellite magnetic exploration. The existing satellite magnetic measurement method fixes the magnetometer on the satellite extension rod, and reduces the influence of the residual magnetism of the satellite body on the measurement result of the magnetometer by increasing the distance between the magnetometer sensing part and the satellite platform body. Therefore, it is of great significance to use effective methods to calculate and eliminate the magnetic interference caused by the satellite platform. [0003] The traditional satellite platform magnetic interference calculatio...
