ABSTRACT:
A method for operating a vibrating gyroscope, wherein the vibrating gyroscope is used as a resonator and forms part of at least one control circuit that excites the vibration gyroscope by feeding an excitation signal with its natural frequency. An output signal can be tapped from the vibrating gyroscope from which the excitation signal is deriveable by filtering and amplification. Upon switching on a sensor arrangement that includes such a vibrating gyroscope, the frequency of the excitation signal is adjusted by exciting the vibrating gyroscope, before the excitation signal is fed, to oscillate freely, measuring the frequency of the free oscillation and feeding the excitation signal to the vibrating gyroscope with the measured frequency.
