ANALYTICAL GYROCOMPASS Russian patent published in 1997 - IPC

FIELD: high-accuracy independent and corrected inertial systems of round and sea navigation, mobile facilities of geological prospecting and mapping. SUBSTANCE: on platform of three-axes gyrostabilizer there are installed two accelerometers, three gyrounits and two amplifiers and gyrounit with wide-range code angle pickup is mounted is mounted. Before start of operation platform is levelled and stabilized in inertial space relative to vertical axis. System of levelling is transferred to storage mode with the help of control unit and two switches at specified time moment and precession angles are fed intro computer where azimuth of platform is determined roughly with the use of constants of unit. By instruction from control unit switch connected circuit of gyroscope setting composed of adder, comparison element, digital-to-analog converter and amplifier to pickup of moment of gyrounit and gyroscope is set into required position. Computer calibrates key parameters of system and makes azimuth of platform more precise. EFFECT: improved operational accuracy. 1 dwg
