FIELD: certification and tests of gyroscopes under laboratory and factory conditions, approval tests . SUBSTANCE: calibrated gyroscope is put on rotary table with input axis orthogonal to celestial axis. Several measurement positions are set by rotation of rotary table about celestial axis and input axis of gyroscope through fixed angles. Number of various values of angle of turn about input axis of gyroscope exceeds two. Summary drift in measurement positions of rotary table is measured. Components of drift of gyroscope are determined. EFFECT: complete calibration of gyroscope, decreased labor input in calibration, enhanced calibration precision. 4 cl, 1 dwg
