Abstract :
Search for improving accuracy of the vibratory gyro by reducing influence of manufacturing imperfections has resulted in differential mode of operation. This operation mode allowed us to drive frequency mismatch as close to null as possible. It has also allowed compensating for the damping cross-coupling by arrangement in essence two opposite directed sensing axes in one ring-like resonator. These results have been obtained by keeping a standing wave between the electrodes. Real and possible advantages of the Coriolis vibratory gyro differential mode of operation for the ring-like resonator have been analyzed in this paper.
