METHOD FOR MEASUREMENT OF GEOMAGNETIC FIELD INDUCTION

摘要

FIELD: magnetic measurements. SUBSTANCE: a set of measurements is made at the nominal rotation velocity of a pick-up, with measurement time being varied. The geomagnetic field induction is measured judging by minimal magnetic meter reeding dispersion in this set of measurements at different time, with measurement time varied and under the influence of periodic magnetic interferences. Further, prior to the start of the measurements, the rotating pick-up angular position is converted into a signal having the period equal to a multiple of the pick-up revolution period and the magnetic meter measurement cycle is synchronized with this signal. EFFECT: increased accuracy of the measurements. 4 dwg
