Vibrating-mass gyroscope systems and method

A vibrating-mass gyroscope system comprising:

• a sensor system comprising a plurality of vibrating-masses and a respective plurality of sets of electrodes respectively coupled to each of the plurality of vibrating-masses, each of the plurality of sets of electrodes being configured to facilitate in-plane motion of a respective one of the plurality of vibrating-masses;
• and
• a gyroscope controller configured to generate:
• drive signals that are provided to drive electrodes of each of the plurality of sets of electrodes to provide an in-plane periodic oscillatory motion of the respective plurality of vibrating-masses along a drive axis in response to a drive axis force along the drive axis of each of the plurality of vibrating-masses generated in response to the drive signals,
• force-rebalance signals that are provided to sense electrodes of each of the plurality of sets of electrodes to calculate a rotation of the vibrating-mass gyroscope system about an input axis, the force-rebalance signals being configured to generate a force-rebalance force along a second axis of each of the plurality of vibrating-masses that is orthogonal to the respective drive axis, and
• quadrature signals that are provided to quadrature electrodes of each of the plurality of sets of electrodes to generate a quadrature force along a third axis of each of the plurality of vibrating-masses that is arranged at approximately 45° relative to the respective drive axis and the second axis to substantially mitigate quadrature effects associated with the respective plurality of vibrating-masses.
