FIRE CONTROL SYSTEM Russian patent published in 2015 - IPC F41G5/14 

FIELD: weapons and ammunition.

SUBSTANCE: fire control system (FCS) comprises a day and night sights having independent stabilisation of the fields of vision in the planes of vertical and horizontal guidance. The control circuit of fields of vision of sights in the fire control system (FCS) is designed in such a way that alignment and synchronised movement of the lines of sight of two sights is constantly provided. At that alignment and synchronised tracking of lines of sight in the FCS is provided using digital signal processing, providing decrease of the error of synchronised tracking, due to the inaccuracy of setting sights in the turret due to nonparallelism of the mounting surfaces, compensation of transmission error of angle from the weapon position sensor and the sensor of the angle of plane of vertical guidance a day sight due to the inaccuracy of the operation of the mechanisms of transmission of angle, as well as to reduce the influence of the temperature error of the sensor.

EFFECT: enhanced functional capabilities.
