Abstract: A gyroscopic system is disclosed comprising at least a vibrating gyroscope, as a first mechanism of angle measurement, designed to provide a first measurement of angle values according to a measurement axis; and a second mechanism of angle measurement, designed to provide a second measurement of angle values according to said measurement axis. First angle values through the first angle measurement mechanism vibrating in a current vibration position and second angle values through the second angle measurement mechanism are provided simultaneously; and from these second angle values corrected on the basis of a comparison of the first and second angle values are deduced. Then the vibration position of the first angle measurement mechanism is changed from the current position to another vibration position.
