Abstract
The present invention provides a correction method and storage medium for the angular error of a superconducting magnetic measuring system. A set of magnetic measuring devices is used to determine the angular installation error between the full tensor magnetic gradient measurement component and the combined inertial navigation system. The method includes: Utilize the total field detector to obtain the total external magnetic field; according to the total external magnetic field, correct the magnetic field of the three-axis magnetometer to obtain the magnetic field component information of the corrected three-axis magnetometer; The magnetic field component information of the meter is compared with the information of the earth's magnetic field model to obtain the magnetic field attitude information of the three-axis magnetometer; the attitude information obtained by the combined inertial navigation is compared with the magnetic field attitude information of the three-axis magnetometer to obtain The target installation error between the two groups of attitudes; correcting the angle installation error according to the target installation error value. The correction method is simple and has high precision, and is especially suitable for application in the field of actual superconducting magnetic measurement.
Description
Technical field[0001]The present invention relates to the technical field of superconducting magnetic test systems, in particular, to a correction method and a storage medium of an angular error of superconducting magnetic measuring system.Background technique[0002]The air superconducting full tone magnetic gradient measurement system is to achieve high efficiency and high precision of underground magnetic minerals by using magnetic abnormal abnormality information caused by magnetic mineral resources during the aerospace platform. 3D positioning and get their spatial distribution information. It has the advantages of fast speed, high efficiency, non-conditioned area conditions and terrain, and other advantages, etc., is one of the important means of resource census and screening to find mineral targets. The full tension magnetic gradient detection system built by Superconducting Quantum Interference Device, Squid, has a significant advantage, and is the important development direct...
