SOLID-STATE WAVE GYROSCOPE Russian patent published in 2019 - IPC G01C19/56 

FIELD: measuring equipment.

SUBSTANCE: invention relates to metrology, in particular, to solid-state wave gyroscopes. Solid-state wave gyroscope comprises a resonator in the form of an axially symmetric thin-wall element capable of vibration, one resonator electrode, a plurality of electrodes of sensors, control electrodes, electronic control unit containing devices for calculating angle, stabilizing amplitude of oscillations, suppressing quadrature oscillations and connected to resonator electrodes, electrodes of sensors, control electrodes. Electronic control unit additionally comprises a comparator with hysteresis, a phase automatic frequency control device, a modulator, an adder, an analogue-to-digital converter and a microcontroller. Outputs of the angle calculation devices are connected through an analogue-to-digital converter with a microcontroller, as well as through a device for suppressing quadrature oscillations with a device for stabilizing amplitude of oscillations. Output of the quadrature oscillation suppression device is connected to the input of the adder, the output of one of the angle calculation devices is connected in series with the comparator with hysteresis and a phase-locked loop, the output of which is connected to an adder via a modulator.

EFFECT: improvement of metrological characteristics due to reduction of time of entry into working mode, increase of accuracy and stability of gyroscope.
