METHOD OF GYROCOMPASSING WITH USE OF GYROSCOPIC TRANSMITTERS OF ANGULAR VELOCITY MOUNTED ON PLATFORM STABILIZED IN PLANE OF LOCAL HORIZON

摘要

FIELD: development of gyrocompasses and course indicating devices of analytical type. SUBSTANCE: two double channel gyroscopic transmitters are mounted on platform in advance so that plane of measurement axes of first gyroscope is parallel to plane of platform and measurement axis of its first channel is directed along axis of platform that coincides with roll stabilization axis in parallel position of planes of platform and outer ring of gimbal suspension. Measurement axis of second channel is directed along axis of platform which is pitching stabilization axis. Measurement axis of second channel of second gyroscope forms right orthogonal measurement trihedron together with measurement axes of first gyroscope. After this angles of inclination, pitch and roll drift of platform are found and angle of true course of roll stabilization axis of platform is computed with the use of analytical expression compensating by it drifts of gyroscopes and platform. EFFECT: widened potential of gyrocompassing with use of gyroscopic transmitters of angular velocity in presence of angular velocities of base. 3 dwg
