A gyroscope structure 41 includes ring structure 42 supported from a central hub 43 by eight compliant support legs 44a to 44h. Primary drive transducers 45a and 45b and secondary drive transducers 46a and 46b are all located around and in spaced relationship with the external periphery of the ring structure 42 to create capacitive gaps and primary pick-off transducers 47a and 47b and secondary pick-off transducers 48a and 48b are all located around and in spaced relationship with the internal periphery of the ring structure 42 to create capacitive gaps. The gyroscope structure 41 includes sixteen capacitor plates 49a to 49p in spaced relationship to the ring structure 42 to create capacitive gaps. Two groups of capacitive plates 49a to 49d and 49i to 49l are all located around the internal periphery of the ring structure 42 and two groups of capacitor plates 49e to 49h and 49m to 49p are all located around the external periphery of the ring structure 42. Each capacitor plate 49a to 49p is arranged to generate a predetermined electrostatic force, which acts upon the ring structure 42 to locally adjust the stiffness of the ring structure 42. The positioning of the transducers 45a to 48b and capacitor plates 49a to 49p reduces the effect of variation a capacitive gap with ring structure 42 due to temperature change, thereby improving the scalefactor of the gyroscope structure.
