发明名称 PROCESS OF GYROCOMPASSING OF THREE-AXES GYROSTABILIZER
摘要 FIELD: azimuthal orientation of mobile objects having control systems with three-axes gyrostabilizers. SUBSTANCE: sensitivity axes of two horizontal gyros are leveled together with platform of gyrostabilizer on which they are mounted at initial position with the use of two horizontal accelerometers. Sensitivity axis of vertical gyro is held in vertical position. Then gyrostabilizer is switched over to mode of gyrocompass by formation of moment of correction proportional to angle of deviation of platform of gyrostabilizer from plane of horizon with the help of torque generator of vertical gyroscope. One of accelerometers is switched over to mode of self-oscillations, its output signal is used to extract components proportional to angular speed and angular acceleration of compass motion of platform of gyrostabilizer that are summed after amplification and conversion and used to form additional moment of correction of vertical gyro. Then after adjustment of platform of gyrostabilizer to direction of meridian one of gyros is switched over to mode of self-oscillations and its information is employed to make azimuthal position of platform of gyrostabilizer more exact. EFFECT: decreased time and improved accuracy while determining direction of meridian by means of three-axes gyrostabilizer. 2 dwg
