SINGLE-GYROSCOPE CORRECTED GYROSCOPIC COMPASS ( VERSIONS ) Russian patent published in 2001 - IPC

FIELD: navigation instrumentation. SUBSTANCE: invention can be used for development of precision single-gyroscope corrected gyroscopic compasses. Gyroscopic compass in accordance with first version has gyroscope-stabilized platform with bottom swing positioned in gimbal suspension with three degrees of freedom. Platform carries free gyroscope and accelerometer. Gimbal suspension is fitted with two stabilization motors and sensor of angle of course. Gyroscopic compass also has integration unit, device for input of external information, three adders, two subtracters, three scalers, units forming " eastern " and vertical angular velocities, units forming " northern " compensating acceleration and analytical stabilization, unit computing inclination of platform around " northern " axis. In correspondence with second version gyroscopic compass includes gyroscope-stabilized platform placed into gimbal suspension with two degrees of freedom. Gyroscope-stabilized platform carries two accelerometers. In this particular case gyroscopic compass incorporates additional subtracter and unit computing " eastern " acceleration. EFFECT: raised precision of gyroscopic compass thanks to elimination of its disturbance while object is maneuvering. 4 cl, 4 dwg
