METHOD OF GEOMAGNETIC FIELD COMPONENTS DETERMINATION Russian patent published in 1996 - IPC

FIELD: methods of geomagnetic field components determination used for geomagnetic field components mapping. SUBSTANCE: method of geomagnetic field components determination provides, that three alternating magnetic fields of different frequency and in orthogonal coordinates system, that is rigidly connected with carrier, are made on carrier and on object in tow with at will oriented orthogonal coordinates system summed magnetic field component is measured. Then each component is separated in accordance to particular sign for its components to determine components of alternating dipole and geomagnetic fields. According to modules of corresponding dipole field they determine direction to point of measurement located on object in tow and values of alternating magnetic fields in two coordinates systems: on carrier and its own field outside - on object in tow. Mutual orientation of the coordinates systems and values of geomagnetic field components produced in coordinates system realized on object in tow are determined and calculated in terms of coordinates system connected with carrier. Method has high accuracy of measurements. Principle of mutual orientation of coordinates systems, one of which is made on carrier and another one is realized on object in tow, is shown on drawing. EFFECT: increase accuracy of measurements. 2 dwg
