Abstract
The method serves to compensates anisotropy in an inertial rotation sensor comprising a metallized vibrating bell (1) having a bias voltage applied thereto, the vibrating bell (1) having an edge (7) electrodes (5.1, 5.2), and the method comprises the steps of measuring, preferably by multiplexing, the anisotropy between the electrodes and of applying to the electrodes a fraction of the bias voltage that depends on the differences measured between the electrodes.
Claims5
A method of compensating anisotropy in an inertial rotation sensor comprising a metallized vibrating bell (1) having a bias voltage applied thereto, the vibrating bell having an edge (7) facing control electrodes and detection electrodes (5.1, 5.2) carried by a stand (3), the method comprising the steps of measuring at least one component of the anisotropy between the detection electrodes, and applying a fraction of the bias voltage to said electrodes as a function of the differences measured between the electrodes.
