METHOD FOR DETERMINATION OF THE AZIMUTH OF THE PLATFORM OF THE TRIAXIAL GYROSTABILIZER BY THE DEVIATION OF THE ANGLE OF ROTATION OF A GYROSCOPE FROM THE CALCULATED VALUE Russian patent published in 2018 - IPC G01C21/18 

FIELD: measuring equipment.

SUBSTANCE: invention refers to gyroscopic systems and can be used for determination of azimuth of the platform of a triaxial gyrostabilizer, for instance, in various navigation systems. Method for determining the azimuth of the platform of a triaxial gyrostabilizer by the deviation of the angle of rotation of the gyroscope from the calculated value is that the platform is roughly lead along the azimuth to the meridian and in this position it is hold by the "memory" mode, one of the gyroblocks is disconnected from the platform stabilization system and used in the two-stage gyrocompass mode. Horizontalization and stabilization of the platform relative to the corresponding stabilization axis is carried out by accelerometer by cutting it off from the gyroblock moment sensor and connecting via an amplifier to the motor of stabilization. In this case, the body of gyroblock of the stabilization system used in the two-stage gyrocompass mode is rotated by the stepping motor towards the meridian according to the calculation program corresponding to the test site, and the platform azimuth is determined by processing information on the signals taken from the gyroblock angle sensor.

EFFECT: technical result of the invention is to increase the accuracy of the platform azimuth determination system, simplify the design and algorithm for determining the azimuth.
