Abstract

The present invention provides a space magnetic field measurement device, measurement system and measurement method without rod extension, the measurement device includes a magnetometer, and the magnetometer includes a plurality of magnetic field detectors distributed on different planes in a three-dimensional distribution. It is used to measure the magnetic field in the space to be measured; and a data processing unit electrically connected to the magnetometer, which receives and processes the data of the space magnetic field measured by the magnetometer; the magnetometer is directly fixedly connected to its supporting part, and measures the magnetic field in space. The invention adopts the magnetometer without extension rod, which is beneficial to the three-axis stable satellite, and will not affect the moment of inertia of the satellite, and will not affect the attitude of the satellite. In the magnetic field measurement system without rod extension, multiple magnetic field detectors of the magnetometer are arranged in different planes to form a three-dimensional distribution pattern, so that the measured magnetic field can be divided into external source field and There are two parts of the internal source field to obtain a more accurate distribution of the magnetic field to be measured.

Description

Technical field[0001]The present invention relates to the field of non-needle rod spatial magnetic field measurement, and more particularly to a spatial magnetic field measuring device, measurement system, and measurement method for no needle rod.Background technique[0002]The magnetic field is the main medium of the daily space interaction energy storage, transmission and release, and is the main factor in the motivational process of electrical particle motion. The detection of spatial magnetic fields will help to study the acceleration mechanism of space high energy electronics, which helps people improve their understanding of the spatial magnetic field and improve the international magnetic field reference model (IGRF). High-precision spatial magnetic field detection can obtain spatial magnetic fields, analysis background magnetic fields and magnetic fields superimposed on the background magnetic field fluctuations. Its measurement data can be used to determine the time evolution...
