Modernized antenna post

The modernized antenna post is designed for stabilization and 360-degree rotation of radar channel of Bagheera- (R-123-02/03-04) system.

Using a radar channel the shipboard fire control system Bagheera- performs scanning, detection and tracking of ground, surface and aerial targets to ranges up to 45 km.

The Karat modernized and produced antenna post is equipped with gyroscopic stabilization system (with digital direct drive tracking systems and torque motors) eliminating the influence of such external factors as rolling, vibration and ship movement. The dimensions of the antenna post allow its application on ships of any class.
