The Russian electronic intelligence system "Gadalka" (Gadalka), manufactured by Groza, was unveiled at an exhibition in Kazan. The system is designed to detect aerial targets and identify reconnaissance drones. It operates in passive mode and does not emit its own radio waves; it only receives signals from detected objects. The system has a range of up to 50 kilometers. To locate targets, it analyzes signals across a wide frequency range—from 890 to 6000 MHz. The system can simultaneously monitor five frequency bands. Information about detected objects is transmitted to service members in real time via the Glaz/Groza battle management system.
