The Vibrating Structure Gyro is a solid state rate sensor tha is designed around a piezoceramic cup that can measure coriolis forces. This allows the VSG to produce a highly accurate output that is proportional to the rate of turn. Electronics for filtering, control, drive and demodulation are all packaged along with a single axis sensing element inside a small package. Wide ranges of input rates (up to 1500° per second) are available.
