Abstract
A method of controlling an inertial rotation sensor has a vibrating resonator having control channels and detection channels. During an operating stage each control channel (C, C) is activated for a control duration and each detection channel (D, D) is activated for a detection duration, in which the control and detection durations are applied at an operating ratio. Duyring a starting stage the control and detection durations are applied at a ratio that is modified in comparison with the operating ratio, so as to increase the control duration.
