  • Patent number: 6805007
    Abstract: A vibrating structure gyroscope comprises a resonant body, a drive transducer for driving resonant motion of the body, a pick-off for producing signals representative of the resonant motion, and a signal processor for extracting z-axis orientation information and x- and y-axis rate information from the signals. The resonant body is planar and the resonant motion takes place in a vibration mode pattern whose orientation angle with respect to the body varies in accordance with z-axis orientation of the body and couples energy into an out-of-plane response mode motion in accordance with rotation of the body about the x- or y-axis. The signal processor resolves the out-of-plane response mode motion with reference to a z-axis orientation signal to extract the x- and y-axis rate information.
