AZIMUTHAL ORIENTATION OF PLATFORM OF TRIAXIAL GYROSTABILISER Russian patent published in 2017 - IPC G01C21/18 

FIELD: measuring equipment.

SUBSTANCE: method of azimuth orientation of the platform of a triaxial gyrostabiliser is that one of the gyroblocks of the stabilisation system of the gyrostabilized platform is used, while the platform is horizontized relative to one of the axis by turning off the accelerometer from the torque gyroblock sensor of the stabilisation loop along this axis and connecting it to the corresponding stabilisation motor through the stabilisation amplifier, and the platform azimuth is determined by information signals equal to the difference between the nominal values of the precession angle of the gyroblock and the corresponding values of the wide-range code sensor of the angle of this gyroblock. At the same time, the angle of deviation of the platform from the horizon is measured with the accelerometer, the differentiation of the measured angle is performed, the current values of the compensation voltage are calculated, which after the conversion from the digital form to the analog one is fed to the torque sensor of this gyroblock.

EFFECT: improving the accuracy and reducing the azimuth determining time.
