Vibrating wheel micromechanical gyro

Silicon micromechanical gyro performance has progressed to the threshold of useful initial applications, at least 1 deg/s. The vibrating wheel on a gimbal (VWOG) is a new gyro design with the promise of improved manufacturability. With a variety of accelerometers from which to choose, the advent of the silicon gyro begins the era of silicon micromechanical inertial guidance.
