MICROMECHANICAL VIBRATORY GYROSCOPE (VERSIONS) Russian patent published in 1997 - IPC

FIELD: navigation, gyroscopes, systems controlling mobile objects, indicators of movement of objects. SUBSTANCE: proposed micromechanical vibratory gyroscope is inserted with active control systems with feedbacks for stabilization of amplitude end phase of excitation oscillations, amplitude and phase of signals along sensitive axis, for stabilization of inherent frequencies of mechanical part of gyroscope, for compensation of dynamic disbalance, for compensation of cross effects of excitation oscillations on output signal. There are given functional diagrams of units realizing above-mentioned functions. It is proposed to manufacture angle pickups on base of field-effect transistors with mobile gates (mechanizers) placed into bridge measurement circuit. EFFECT: increased precision of gyroscope. 11 cl, 13 dwg
