Abstract
A gyroscope structureincludes ring structuresupported from a central hubby eight compliant support legstoPrimary drive transducersandand secondary drive transducersandare all located around and in spaced relationship with the external periphery of the ring structureto create capacitive gaps and primary pick-off transducersandand secondary pick-off transducersandare all located around and in spaced relationship with the internal periphery of the ring structureto create capacitive gaps. The gyroscope structureincludes sixteen capacitor platestoin spaced relationship to the ring structureto create capacitive gaps. Two groups of capacitive platestoandtoare all located around the internal periphery of the ring structureand two groups of capacitor platestoandtoare all located around the external periphery of the ring structureEach capacitor platetois arranged to generate a predetermined electrostatic force, which acts upon the ring structureto locally adjust the stiffness of the ring structure The positioning of the transducerstoand capacitor platestoreduces the effect of variation a capacitive gap with ring structuredue to temperature change, thereby improving the scalefactor of the gyroscope structure.
