Abstract

The invention provides a detection device used for a satellite space magnetic field. The device includes a digital flux gate magnetometer, a colossal magnetoresistance magnetometer and a power supplycontrol electric circuit. The digital flux gate magnetometer is connected with a communication interface of the colossal magnetoresistance magnetometer and the power supply control electric circuit, the input voltage of the digital flux gate magnetometer and the colossal magnetoresistance magnetometer is controlled by the power supply control electric circuit through the satellite signal, the synchronized clock signal of running of the magnetometer is provided simultaneously, and the magnetic field detection data outputted by the magnetometer is packed and arranged and then inputted to the satellite. The low frequency signal and high frequency signal of the satellite space magnetic field can be detected and obtained simultaneously by the detection device, and the relative independent signal processing can be performed.

Description

technical field [0001] The invention relates to the field of space detection, in particular to a detection device for satellite space magnetic field. Background technique [0002] Magnetosphere-ionosphere-thermosphere is a complex space environment where plasma and neutral gas coexist and are closely coupled with each other. It is the main area where disastrous space weather caused by violent solar activities occurs. It has an important influence on the normal operation of the region; therefore, the detection research in this area contains great scientific significance and has important application prospects. [0003] In the space physics research of the magnetosphere-ionosphere-thermosphere, a fluxgate magnetometer is usually used for vector measurement of the space magnetic field. Fluxgate technology was first developed by the Germans in 1930, and began to enter the practical stage during the same period. It has a large range of magnetic field detection (+ / -65000nT), and...
