1. A resonator gyroscope, comprising:

  • an isolated resonator having a first and a second differential vibration mode;

    a baseplate supporting the isolated resonator;

    a plurality of excitation electrodes affixed to the baseplate for exciting the first differential vibration mode;

    a plurality of sensing electrodes affixed to the baseplate for sensing movement of the gyroscope through the second differential vibration mode; and

    a plurality of bias electrodes affixed to the baseplate for trimming isolation of the resonator and substantially minimizing frequency split between the first and second differential vibration modes.
