Problems solved by technology

[0003] At present, the measurement of geomagnetic elements can be divided into three categories: the first category is represented by fluxgate sensors, which can directly obtain geomagnetic three-component information, but there are orthogonality errors, temperature drift, and the inability to perform absolute observations, etc. Problem; the second category is the combined measurement of the fluxgate sensor and theodolite. This type of magneto

The measuring system of the geomagnetic elements comprises a geomagnetic element sensor, an element magnetometer host and a connecting unit, wherein the geomagnetic element sensor comprises a total field sensor and a uniform magnetic field generator; one end of the total field sensor is fixed in the center on the inner side of the uniform magnetic field generator in a clamping manner; the other end of the total field sensor is connected with the uniform magnetic field generator; the element magnetometer host comprises a measuring module and a constant current source system; the measuring module comprises an excitation source, a signal conditioning module and a magnetic field measuring module; the excitation source drives the total field sensor to send a signal; the connecting unit comprises a signal transmission line and a power supply cable; the signal transmission line is connected with the total field sensor and the measuring module; the power supply cable is connected with the uniform magnetic field generator and the constant current source system; the constant current source system supplies power for the uniform magnetic field generator via the power supply cable.

Description

technical field [0001] The invention relates to the field of geomagnetic measurement, in particular to a system and method for measuring all elements of geomagnetism. Background technique [0002] The geomagnetic field is one of the basic physical fields reflecting the material distribution and geological structure of the earth, and it can reveal the physical and chemical processes inside the earth. The magnetometer is the main scientific instrument for measuring the geomagnetic field, and it is widely used in earth science research, geological and resource exploration, aerospace, military exploration and other fields. There are seven main elements of geomagnetic field information: total field, horizontal component, northward component, eastward component, vertical component, magnetic inclination and magnetic declination. The conventional total geomagnetic field measurement can only determine the distribution and structure of the magnetosphere, but the geomagnetic elements ...
