Abstract:
1. A method for operation of a vibration gyroscope, which includes a resonator and forms a part of at least one control loop which supplies an exciter signal at a natural frequency to excite the vibration gyroscope, wherein an output signal is tapable from the vibration gyroscope and the exciter signal is derivable from said output signal by filtering and amplification, the method comprising: switching on a sensor arrangement having the vibration gyroscope; exciting the vibration gyroscope sequentially at a plurality of frequency ranges to oscillate freely before the exciter signal is supplied to set a frequency of the exciter signal, after the sensor arrangement with the vibration gyroscope has been switched on; measuring a frequency of the freely oscillating gyroscope; and supplying the exciter signal to the vibration gyroscope at the measured frequency of the freely oscillating gyroscope.
