SPATIAL INTEGRATING SOLID-STATE WAVE GYROSCOPE Russian patent published in 2021 - IPC G01C19/56 

FIELD: gyroscopes.

SUBSTANCE: invention relates to gyroscopic instrument manufacture and can be used for measuring the angular velocities of moving objects. The spatial integrating wave solid-state gyroscope comprises a resonator in the form of an axisymmetric thin-walled element capable of vibration, one resonator electrode, multiple sensor electrodes, control electrodes, an electronic control unit containing angle calculation, oscillation amplitude stabilisation, and quadrature oscillation suppression apparatuses, and connected with the resonator electrodes, sensor electrodes, control electrodes, wherein the electronic control unit comprises a comparator with hysteresis, a phase-locked frequency control apparatus, a modulator, an adder, an analog-to-digital converter, a microcontroller, wherein the outputs of the angle calculation apparatuses are connected with the microcontroller via the analogue-to-digital converter, as well as via the quadrature oscillation suppression apparatus with the oscillation amplitude stabilisation apparatus. The output of the quadrature oscillation suppression apparatus is connected with the input of the adder, the output of one of the angle calculation apparatuses is series-connected with the comparator with hysteresis and the phase-locked frequency control apparatuses, the output whereof is connected with the adder via the modulator. The resonator is made in the form of a spatial evacuated module consisting of an outer and an inner spheres placed concentrically one inside the other, made of a magnetic material with a mutually opposite direction of magnetisation, wherein a power source, electromagnetic centering windings, and a control unit are placed in the inner sphere, and control electrodes and an auxiliary electrode are placed on the outer side of the inner sphere. Sensors for measuring the position of the standing wave are placed on the inner side of the outer sphere and electromagnetic centering windings are placed on the outer side of the outer sphere, and a spatial standing wave is excited in the thin-walled sphere made of a material with small internal friction parameters, enveloping the inner sphere from the outside via non-magnetic sleeves.

EFFECT: expanded functional capabilities of the solid-state wave gyroscope due to the provided possibility for the proposed design of a spatial integrating solid-state wave gyroscope to determine the three components of rotational motion of a moving object, characterising the spatial angular position thereof - the parameters of orientation of the moving object.
