IMAGE STABILIZATION SYSTEM ON MOVABLE BASE Russian patent published in 2020 - IPC G02B27/64 

FIELD: optical instrument making.

SUBSTANCE: invention can be used in gyrostabilized devices placed on movable objects to increase stabilization accuracy at large guidance angles and operational reliability during operation. Disclosed is an image stabilization system on a movable base, comprising an indicator gyroscopic platform with a mirror mounted thereon, gimbals, made in the form of external and internal frames, three-stage gyroscopic reference unit (GRU) with torque sensors (TS) and rotor angle sensors (RAS) GRU.

EFFECT: technical result consists in improvement of accuracy and reliability of stabilization system and is achieved by introducing in channel stabilization along axis of horizontal guidance device correction coefficient of transmission, eliminating increase in horizon stabilization error when platform with gyroscopic reference unit (GRU) deviates from zero position vertically, as well as change of protection device circuit against overheating of stabilization sensors, which provides their protection in case of mechanical jamming and stable automatic restoration of stabilization system after elimination of external mechanical action.
