DEVICE FOR MEASURING FLUX DENSITY OF MOBILE-OBJECT GEOMAGNETIC FIELD

摘要

FIELD: measurement technology; geomagnetics. SUBSTANCE: device that may be used for mineral exploration, space investigations to measure magnetic field in near-earth space and magnetic field of planets, for magnetic navigation to measure speed and to locate position of ships, and the like has object-disposed three-component magnetometering transducer, three amplifier-converter units, variable-voltage generator, angle measuring unit, recording unit, and adder data processing unit, all interconnected in certain way. Device functions to determine flux density of geomagnetic field using for the purpose measured projections of magnetic flux density vector, known Poisson parameter, projections of magnetic flux density vector from tight saturation of object in absence of data on angles of heading, list, and pitch of object, and to compensate for vector magnetic flux density projection from object saturation at location point of three-component transducer. EFFECT: reduced error in geomagnetic flux density measurements. 1 cl, 1 dwg
