The invention provides a superconducting magnetic measurement system angle error correction method and a storage medium. An angle installation error between a full-tensor magnetic gradient measurementassembly and combined inertial navigation is determined by using a set of magnetic measurement device. The method comprises the following steps: acquiring an external magnetic field total field by using a total field detector; correcting the magnetic field of a three-axis magnetometer according to the external magnetic field total field to obtain corrected magnetic field component information ofthe three-axis magnetometer; comparing the magnetic field component information of the three-axis magnetometer with earth magnetic field model information to obtain magnetic field attitude informationof the three-axis magnetometer; comparing the attitude information obtained by the combined inertial navigation with the magnetic field attitude information of the three-axis magnetometer to obtain atarget installation error between the two groups of attitudes; and correcting the angle installation error according to the target installation error value. The correction method is simple, high in accuracy and particularly suitable for being applied to the field of actual superconducting magnetic measurement.
Description
technical field [0001] The invention relates to the technical field of superconducting magnetic measuring systems, in particular to a method for correcting angle errors of a superconducting magnetic measuring system and a storage medium. Background technique [0002] The aeronautical superconducting full tensor magnetic gradient measurement system is equipped with magnetic measurement equipment on the aerial platform, and uses the geomagnetic anomaly information caused by magnetic mineral resources obtained during the flight, so as to realize high-efficiency and high-precision measurement of underground magnetic ore bodies. Three-dimensional positioning, and obtain their spatial distribution information. It has the advantages of fast speed, high efficiency, and is not affected by the conditions of the survey area and terrain fluctuations. It is one of the important means for resource census and screening of prospecting target areas. The full tensor magnetic gradient detecti...
