Problems solved by technology

[0002] At present, the Overhauser proton magnetometer is mainly used in the domestic marine daily variable station. Taking advantage of the accuracy and resolution of the Overhauser proton magnetometer, it can well meet the daily change measurement. , a certain percentage of delivery data is missing
On the other hand, the Overhauser proton magnetometer can only measure the total amount of geomagnetism, but cannot obtain all the elements of geomagnetism. In this respect, it is far behind the western powers, and its value to ocean magnetic field data is also greatly reduced.
[0003] In addition, the proton magnetometer will have a polarization process during the working process. This process requires a relatively stable magnetic field. When the proton magnetometer is in a rotating state, the direction of the magnetic field felt by the proton magnetometer changes greatly, which will cause The measurement of the proton magnetometer is unstable

Abstract

The invention discloses a geomagnetic field component measuring method and a full-parameter marine geomagnetic diurnal variation station. The full-parameter marine geomagnetic diurnal variation station comprises a proton magnetometer, a fluxgate sensor, an inclination sensor, a sleeve and a directional empennage; the directional empennage is connected with the sleeve through a hoop; the proton magnetometer, the fluxgate sensor and the inclination sensor are all arranged in the sleeve; the proton magnetometer is used for measuring the total amount of the geomagnetic field; and the fluxgate sensor and the inclination sensor are used for measuring the component of a geomagnetic field. According to the invention, the proton magnetometer is arranged, so the total amount of the geomagnetic fieldcan be accurately measured; the fluxgate sensor is combined with the inclination sensor to measure the component of the geomagnetic field; and in addition, the directional empennage is additionally arranged outside the sleeve and can properly adjust the posture of the sleeve, so that the sleeve is always in an incident flow state in the ocean, the rotation of the proton magnetometer in the measurement direction is effectively reduced, and the measurement of the proton magnetometer is more stable.

Description

technical field [0001] The invention relates to the technical field of geomagnetic field measurement, in particular to a method for measuring geomagnetic field components and a full-parameter marine geomagnetic diurnal variable station. Background technique [0002] At present, the Overhauser proton magnetometer is mainly used in the domestic marine daily variable station. Taking advantage of the accuracy and resolution of the Overhauser proton magnetometer, it can well meet the daily change measurement. In , a certain proportion of delivery data is missing. On the other hand, the Overhauser proton magnetometer can only measure the total amount of geomagnetism, but cannot obtain all the elements of geomagnetism. In this respect, it is far behind the western powers, and its value to ocean magnetic field data is also greatly reduced. [0003] In addition, the proton magnetometer will have a polarization process during the working process. This process requires a relatively st...
