VIBRATING RATE GYRO WITH SLAVING OF DETECTION FREQUENCY TO EXCITATION FREQUENCY

摘要

The invention relates to a rate gyro comprising at least one mass (M) which can vibrate along an axis x at a resonance excitation frequency Fx and which can vibrate along an axis y, which is perpendicular to axis x, at a resonance detection frequency Fy, under the effect of a Coriolis force produced by means of rotation around an axis z which is perpendicular to axes x and y. The invention also comprises a mass (M) vibration interference signal generator which is connected to the aforementioned mass and a loop for slaving resonance frequency Fy such that Fy is equal to or almost equal to Fx while the rate gyro is being used.
