Abstract

A solid state vibrational gyroscope comprises a resonator bell 21 having piezoelectric drive transducers 1a and 1b aligned with antinodes of a natural mode of vibration of the resonator bell. This is achieved by either constructing the resonator bell such that it is deliberately out of balance so that the antinodes are aligned with the transducers 1a, 1b, or alternatively by balancing the resonator bell such that the antinodes of the natural mode of vibrations always corresponds to the position of the drive transducer regardless of its location. The invention further provides for balancing the fully assembled resonator bell using the drivers 1a, 1b and sensors 2a, and 2b in the balancing process. <IMAGE>
