Abstract
A rate gyro or a gyroscope includes a resonator having four mutually parallel identical beams integral with a common square base and projecting from the base at corners of a virtual square. The beams have a same resonant frequency in two directions parallel to the two sides of the square base. It further has first transducers for vibrating each beam in a first direction orthogonal to the beams, connected to a driving circuit and second transducers for detecting an amplitude of vibration of the beams in a second direction each orthogonal to a respective first direction.
