FIELD: magnetometric measurements.
SUBSTANCE: invention relates to the field of magnetometric measurements and can be used for calibration operations of three-component fluxgate magnetometers. Successive arbitrary rotations of the block of flux-gates in space are performed directly in the geomagnetic field with the measurement of the totality of three projections of the magnetic induction vector. Measuring information is accumulated when the spatial position of the magnetometer block changes. The deviation angles of the magnetically sensitive axes of the three-component magnetometer ferroprobes from its own geometrical axes of the orthogonal basis are determined from the accumulated measurement results by the method for their iterative variation. At the same time, successive approximation to the true values of small angular parameters is carried out with finding the minimum of the target function.
EFFECT: reducing the measurement error of three-component flux-gate magnetometers by determining with high accuracy the small angular parameters of the deviation of the sensitivity axes of three-component flux-gate sensors from orthogonal axes and taking them into account during further processing of the measurement results.
