FIELD: physics; measuring.
SUBSTANCE: invention concerns to field of measuring technics and can be used in instrument making and mechanical engineering for measuring of angular velocity. The gyroscope contains a piezoelectric plate with inertial masses generated on one side, not less than one interdigitated transducer and not less than one reflecting structure of the resonator on the superficial ultrasonic waves and also the driver on the superficial ultrasonic waves consisting not less than from one interdigitated transducer and not less than from one reflecting structure so the superficial ultrasonic wave raised by the driver transits through reflecting structures of the resonator and the inertial masses generated in immediate proximity from them. The interdigitated transducers and reflecting structures of the driver can be generated on the one hand piezoelectric plates and interdigitated transducers and reflecting structures of the resonator on the other hand and working frequencies of the driver and the resonator differ, for example, not less than twice.
EFFECT: increase of a measurement accuracy of angular velocity.
