Vibrating structure gyroscope

A vibration gyro (English Vibrating Structure Gyroscope VSG) is a sensor for measuring the rate of rotation and thus the rotation angle of a body in space. The measurement error cheaper sensors amounts to less than 10 ° / h

A vibration gyro is made of a vibratory system, for example a quartz oscillator. Is the quartz rotated perpendicular to a deflection direction of the angular velocity ω, Coriolis force F acting ~ da / dt ω x perpendicular to the oscillating system. The distortion can be detected by a piezoelectric transducer.

The word gyroscope is here, as well as the fiber or laser gyro, taken from the gyro instrument which was traditionally used to determine the orientation in space.

The halteres of insects operate on the principle of a vibrating gyroscope.
