ABSTRACT:
The present invention discloses a gyroscope comprising an isolated resonator including a post proof mass and counterbalancing plate. One or more double beam flexures each interconnect the counterbalancing plate and the proof mass with a first and a second beam attached to the post proof mass and a third and a fourth beam attached to the counterbalancing plate. A baseplate is affixed to the resonator by the double beam flexures. The counterbalancing plate and the proof mass transfer substantially no net momentum to the baseplate when the resonator is excited.
