1. A resonator gyroscope, comprising:

  • an isolated resonator including;

    a proof mass;

    a counterbalancing plate having a planar region; and

    one or more flexures interconnecting the proof mass and the counterbalancing plate;

    where the planar region extends toward the proof mass beyond attachment points of the one or more flexures interconnected to the counterbalancing plate;

    a baseplate affixed to the resonator by the one or more flexures; and

    drive and sense electrodes affixed to the baseplate proximate to the planar region of the counterbalancing plate for exciting the resonator and sensing movement of the gyroscope, wherein the isolated resonator transfers substantially no net momentum to the baseplate when the resonator is excited.
