FIELD: gyroscopes.
SUBSTANCE: group of inventions relates to the calibration of Coriolis vibration gyroscopes using two displacement voltage measurements. The method for calculating the angular velocity of a Coriolis vibration gyroscope includes applying the first input voltage to the Coriolis vibration gyroscope (101) at the first displacement voltage (P0); applying the second input voltage to the Coriolis vibration gyroscope (101) at the second displacement voltage (P0'), while the second displacement voltage (P0') differs from the first displacement voltage (P0); registration of the difference in the responses of the Coriolis vibration gyroscope (101) to the first displacement voltage (P0) and the second displacement voltage (Р0') and determination of the angular velocity of the Coriolis vibration gyroscope (101) as a function of the response difference and the correction term (C).
EFFECT: calibration or recalibration of Coriolis vibration gyroscopes with reference to external means for correction of vibration gyroscope drift (indicated displacement) and distorted scale coefficients.
