METHOD OF DETERMINATION OF POSITION OF VECTOR OF KINETIC MOMENT OF CONTACTLESS GYROSCOPE Russian patent published in 1996 - IPC

FIELD: precision instrument engineering. SUBSTANCE: invention is designed for use in contactless (electrostatic, magnetic) gyroscopes as part of orientation and navigation systems of moving object. Method of determination of direction cosines of vector of kinetic moment of gyroscope is based on use of signals of beats of dynamically unstabilized spherical rotor with reference to supporting elements along three mutually orthogonal suspension axes Phase shifts through angle π/2 between first and second signals, between second and third signals and between third and first signals are input. Then phase-shifted signals are multiplied: first one with second one, second one with third one and third one with first one. Direction cosines of vector of kinetic moment are judged by constant components of these products. EFFECT: improved accuracy of determination of position of vector of kinetic moment of contactless gyroscope. 1 cl, 3 dwg
