CALIBRATION METHOD OF VIBRATION GYROSCOPE Russian patent published in 2019 - IPC G01C19/5776 

FIELD: measurement technology.

SUBSTANCE: group of inventions relates to a calibration method of a vibration gyroscope. Method of vibrating gyroscope calibration includes stages, at which excitation of vibration is performed along resonance structure excitation axis, wherein axis of excitation is positioned in first angular position, vibration reading of resonance structure on first axis of reading resonance structure at the time when excitation axis is positioned in first angular position, generating a first reading signal indicating the readout vibration of the resonant structure on the first reading axis, continuously rotating the excitation axis about the resonant structure to a second angular position, reading vibration of the resonant structure on the second axis of reading the resonant structure at a time when the excitation axis is positioned in the second angular position, generating a second read signal indicating the readout vibration of the resonance structure on the second reading axis, and summation of the first readout signal with the second reading signal in order to extract the gyroscope offset.

EFFECT: high accuracy of measuring speed of angular rotation of a vibration gyroscope.
