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.
