DEVICE FOR DETERMINING COMPONENTS OF MAGNETIC FIELD OF THE EARTH AND COMPONENTS OF ITS OWN MAGNETIC FIELD WHILE ON BOARD OF MOVING FERROMAGNETIC CARRIER

摘要

FIELD: magnetometry; related to devices operating on-board of moving carrier with inherent magnetic field unspecified by its characteristics. SUBSTANCE: device makes it possible to find direction of induction vector of magnetic field of the Earth in given system of coordinates and to determine components of own magnetic field of carrier. Formulated problem is solved with the aid of adiabatic equations. For realization of such possibility there is used unit of magneto-sensitive converters incorporating component meters enabling three various components of magnetic field as minimum to be determined. It is also possible to mount unrestricted number of component meters oriented at will which enhances noise immunity but required usage of additional meters and of more complex algorithms for information processing. Mentioned measurements are carried out together with measurement of angles characterizing orientation of carrier in specified system of coordinates which amounts to one cycle. After performance of series of measurements composed of several cycles system of vector adiabatic equation is set up which solution enables sought-for values to be determined. EFFECT: higher results of determination.
