Abstract
One embodiment of the invention includes a vibrating-mass gyroscope system. The system includes a sensor system comprising a vibrating-mass and a plurality of electrodes coupled to the vibrating-mass that are configured to facilitate in-plane motion of the vibrating-mass. The system also includes a gyroscope controller configured to generate a drive signal that is provided to a first set of the plurality of electrodes to provide an in-plane periodic oscillatory motion of the vibrating-mass along a drive axis, to generate a force-rebalance signal that is provided to a second set of the plurality of electrodes to calculate a rotation of the vibrating-mass gyroscope system about an input axis, and to generate a quadrature signal that is provided to a third set of the plurality of electrodes to substantially mitigate quadrature effects associated with the vibrating-mass.
