VIBRATORY GYROSCOPE Russian patent published in 1998 - IPC

FIELD: solid-state electrical instruments used as sensors of moving-object angular velocity for navigation and automatic-control systems, especially space- saving ones. SUBSTANCE: gyroscope has solid- state member of ferroelectric ceramics with smeared phase transition in the form of monolithic cross-like-section bar with two pairs of solid electrodes and two pairs of interdigital ones. Solid electrodes are interconnected in parallel and connected to output of first generator, Interdigital electrodes are connected to frequency-setting circuits of second and third generators. Outputs of second and third generators are connected to inputs of mixer whose output is connected to detector input; detector output is connected to indicator input. EFFECT: improved stability and noise immunity of vibratory gyroscope. 5 dwg
