METHOD OF INDEPENDENT AZIMUTHAL ORIENTATION OF PLATFORM OF THREE-AXIS GYROSTABILISER ON MOVABLE BASE Russian patent published in 2015 - IPC G01C21/18 

FIELD: instrument engineering.

SUBSTANCE: measurements are carried out in the inertial mode of functioning of the system of the platform stabilisation relative to the vertical axis. Before starting the measurements the platform is roughly mounted and held in the desired initial position in azimuth. The azimuthal position determined by information on currents of feedback and angles of rotation of standard gyro unit disconnected from the stabilisation system and switched on in a mode of angular velocity sensor. Stabilisation and levelling of the platform in measurements is carried out by the corresponding accelerometer connected through the amplifier to the stabilisation engine.

EFFECT: possibility of determining the azimuthal position of the gyro-stabilised platform under conditions of azimuthal displacements of the base, simplification of design, reduction of time, and increase in accuracy of determining the azimuthal position of the platform.
