The invention discloses a method and a system for carrying out reduction processing on measurement data of geomagnetic data. The method comprises steps of determining position coordinates of three geomagnetic stations around a to-be-solved point, wherein the distances from the three geomagnetic stations to the to-be-solved point are set to be within a threshold range and the triangle formed by theposition coordinates of the three geomagnetic stations is an acute triangle; acquiring measurement data of the three geomagnetic stations; according to the position coordinates and the measurement data of the three geomagnetic stations, determining a triangular interpolation method observation function; and according to the position coordinates and the observation data of the three geomagnetic stations, by use of the triangular interpolation method observation function to determine geomagnetic data of the to-be-solved point. According to the invention, precision of the reduction processing can be improved; reduction processing time is shortened; and reduction processing efficiency is improved.
Description
technical field [0001] The invention relates to the field of geomagnetic measurement, in particular to a method and system for generalizing and processing measurement data of geomagnetic stations. Background technique [0002] The earth's magnetic field is a three-dimensional vector physical field formed by the superposition of various magnetic field components produced by magnetic rocks inside the earth and current systems distributed inside and outside the earth, and is a function of space position and time. Due to the different origins of the magnetic field, the spatial distribution and temporal variation of various magnetic field components are also quite different. According to the location of the field source, the geomagnetic field can be divided into two parts: the internal source field and the external source field. [0003] The internal source field originates from the magnetic matter and current below the surface of the earth, including the core field and the crus...
