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. First angle values through the first angle measurement mechanism and second angle values through the second angle measurement mechanism are then provided simultaneously; and from these first angle values corrected on the basis of a comparison of the first and second angle values are deduced.
