Abstract
The present invention discloses a resonator gyroscope comprising a resonator including two bodies, each with a center of mass and transverse inertia symmetry about an axis that are substantially coincident and each supported by one or more elastic elements and wherein the bodies together forming two differential rocking modes of vibration transverse to the axis with substantially equal frequencies and wherein the two bodies transfer substantially no net momentum to the baseplate when the resonator is excited. The gyroscope further includes a baseplate affixed to the resonator by the one or more elastic elements and sense and drive elements each affixed to the resonator and baseplate.
