Claim Text:
1. An axisymmetrical Coriolis vibratory gyroscope, comprising: a thin-walled resonator of hemispherical or cylindrical or toroidal shape, fastened centrally on a stem located within the resonator; a wall of the resonator having holes arranged around the stem, a number of holes based on “4nk”, where “k” is an integer, “n” is an order of vibration modes of the thin walled resonator, and an angle between adjacent holes is equal to “π/ wherein the stem is shaped as a solid or partially hollow cylinder, and is rotationally symmetric about its longitudinal axis and is fastened on a base; electrodes are arranged on the resonator wall or alongside the resonator wall for excitation and measurement of two vibration modes, with leads passing from the electrodes through holes in the resonator wall; the base includes a seating for the resonator stem, and leads pass from the outside of the base through the base, the leads being electrically-insulated and sealed relative to the base; and the leads that pass through the base are connected to the leads that pass from the electrodes, thereby allowing signals to pass from outside the base, through the base, through the holes and to the electrodes.
