METHOD OF MEASUREMENT OF THE MAGNETIC COURSE OF A MOBILE OBJECT AND THE DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01C17/30 

FIELD: instrument engineering.

SUBSTANCE: group of inventions refers to navigational instrument engineering and can be used in building of course-setting independent magnetic compasses. Magnetic course of a mobile object is measured by the values of the output signals of a single ferro probe, the first and second permalloy cores of which, with excitation windings and, respectively, with the first and second signal windings are disposed at an angle to each other, the excitation winding of the ferro-probe is fed from a generator of unipolar pulses, the polarity sign of which is changed in accordance with the direction of the vector of the measured magnetic field, and the numbers of the output signals corresponding to the numbers of the output windings, signs of their polarity and amplitude ratio determine one of the four sectors of the measured magnetic course, and the ratio of the amplitude of the output signals within the sector determines the magnetic course.

EFFECT: simplification of the algorithm for transforming the initial information, the design of the magnetic compass, and increase in the accuracy of calculating the magnetic course.
