A single axis rate sensor (10) including a substantially planar vibratory resonator (16) having a substantially ring or hoop-like structure with inner (24) and outer peripheries extending around a common axis, drive means (18) for causing the resonator to vibrate in a Costheta vibration mode, carrier mode pick-off means (20) for sensing movement of the resonator in response to said drive means (18), pick-off means (36) for sensing resonator movement induced in response to rotation of the rate sensor about the sensitive axis, drive means (38) for mulling said motion, and support means (22) for flexibly supporting the resonator (16) and for allowing the resonator (16) to vibrate relative to the support means (22) in response to the drive means, and to applied rotation wherein the support means (16) comprises only L support beams, where L<>3x2<K-1>, L>2 and K=1, 2 or 3.
