FIELD: gyroscopes. SUBSTANCE: self-excited oscillations of rotor relative to shaft are built up in vibratory gyroscope, difference of frequencies of self-oscillations of rotor and shaft rotation are found by which absolute angular speed of base about axis of gyroscope shaft is judged. Measurement of deviations of rotor and determination of angular speeds of base around axes developed in rotation plane of shaft with reference to direction of components of speeds through angle corresponding to difference to frequencies of self-excited oscillations of rotor and rotation of shaft are carried out. EFFECT: provision for indication of absolute angular speed around axis of shaft of rotor vibratory gyroscope and increased accuracy of indication in plane perpendicular to axis of shaft. 1 dwg
