METHOD OF MEASURING MAGNETIC FIELD OF SURFACE OR UNDERWATER OBJECT WITH ADJUSTMENT OF ELECTROMAGNETIC COMPENSATION SYSTEM THEREOF Russian patent published in 2013 - IPC G01R33/02 

FIELD: electricity.

SUBSTANCE: when an object manoeuvres on a fixed stand, the object being equipped with sections of demagnetising windings, sensors mounted at the bottom of said stand, based on data from means of tying coordinates of sensors of the stand to coordinates of the object, magnetic field parameters of the object recorded in form of voltage or current signals transmitted over a radio link or another way, and magnetic field of the object is determined from results of processing signals obtained from said sensors, based on the configuration of the object and sensors of the stand. When the object manoeuvres in fixed time intervals through an automatic apparatus for controlling current in said sections, controlled short-term increase or reduction of current in said sections of demagnetising windings of the object is carried out and parameters of the object are determined from results of processing signals on the detected magnetic field of the object and changes thereof obtained from the sensors of the stand.

EFFECT: faster adjustment of a system for electromagnetic compensation of the magnetic field of a surface or underwater object manoeuvring on a stand, shorter time spent by the object on the stand.
