METHOD AND SYSTEM FOR GYROSCOPIC MEASUREMENTS WITH USAGE OF VIBRATION GYROSCOPE Russian patent published in 2014 - IPC G01C19/567 

FIELD: measurement equipment.

SUBSTANCE: invention relates to vibration gyroscopes. The gyroscopic system performs measurements with the help of a vibration gyroscope, which vibrates in the first position of vibration and sends a signal of measurements. A periodic control signal is sent to the vibration gyroscope within a certain temporary period, and this signal provides for rotation of geometric position of vibration in the first direction within a part of temporary period with transition from the first to the second position in accordance with the first speed profile, rotation of geometric position of vibration in the second direction opposite to the first direction, within the remaining part of temporary period with transition from the second to the first position in accordance with the second speed profile. Speed profiles set variations of position change speed. Results of measurements performed by the system are formed, on the basis of a corrected signal produced by subtraction of the control signal from the signal of gyroscope measurements.

EFFECT: invention provides for increased accuracy of measurements.
