ABSTRACT:
The invention relates to a method for monitoring a vibrating gyroscope which represents a resonator and forms part of at least one control loop that excites the vibrating gyroscope with its natural frequency by supplying an excitation signal. An output signal can be extracted from the vibrating gyroscope, the excitation signal being derived from said output signal by means of filtering and amplifying. According to the invention, the quality of the resonator is measured. If the measured quality is below a threshold value, an error message is generated.
