FIELD: mining.;SUBSTANCE: in housing of the well device a three-axes unit accelerometer/magnetometer is installed, using it the projections gx, gy, gz of known vector of gravity force acceleration is installed, the projections mx, my, mz of full vector of geomagnetical field intensity are measured, they are used to determine azimuth α, zenithal θ and viewing ϕ angles. Wherein a priori determined numerical values of small angular parameters of deviation of sensor sensitivity axes are used: χA, δXA, δYA, σ1A, σ2A for three-axes accelerometer and χF, γF, δXF, δYF, σ1F, σ2F for three-axes magnetometer.;EFFECT: reduced error of measurements of directional systems due to consideration of small angular parameters of deviation of the sensitivity axes of three-component ferroprobe and accelerometer sensors of the directional systems from the orthogonal axes during the measurement results processing.;2 dwg, 2 tbl
