Abstract

A method and system for monitoring a sensor arrangement comprising 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 is tapable from the vibrating gyroscope from which the excitation signal is derivable by filtering and amplification.
