Automated Engineer Obstacle System "CHAHARNYK"

A Modular Solution for Countering Fiber-Optic FPV Drones

PURPOSE OF “CHAHARNYK”

The primary purpose of the system is to protect assets and personnel by ensuring the timely detection and effective neutralization of FPV drones that use fiber-optic control links.

THE PROBLEM IT ADDRESSES

Fiber-optic FPV drones bypass conventional radio-frequency countermeasures. A fiber-optic control link: - operates independently of radio communications; - does not generate a conventional radio-frequency control signal; - maintains a stable connection in electronic warfare (EW) environments; - requires additional physical countermeasures.
The “CHAHARNYK” Automated Engineer Obstacle System is a specialized suite of engineering and technical equipment designed to counter FPV unmanned aerial vehicles (UAVs) that use fiber-optic control links.

Protection must be effective not only across the radio-frequency spectrum, but also on the ground.

“CHAHARNYK” is designed for:
  • protecting firing positions, command posts, and personnel accommodation areas;
  • safeguarding critical military infrastructure;
  • enhancing the security of civilian facilities and frontline communities facing an elevated UAV threat.
“CHAHARNYK” can be deployed either as a stand-alone solution or as part of integrated systems for the engineering preparation of positions. It provides continuous 24/7 operation, can be adapted to local terrain conditions, and is scalable to meet customer requirements.

“CHAHARNYK” PROVIDES:

DETECTION

Acoustic detection of FPV drones as they approach the monitored area;

IDENTIFICATION

Automated threat identification based on the distinctive acoustic signatures of motors and propellers;

NEUTRALIZATION

Deployment of a physical engineer obstacle that mechanically engages and severs the drone’s fiber-optic cable during flight.
OBSTACLE CONFIGURATION CAN BE ADAPTED TO THE PROTECTED ASSET AND LOCAL TERRAIN:
  • “CHAHARNYK” can be used for:

  • blocking likely aerial avenues of approach;
  • protecting access routes and passageways;
  • reinforcing the perimeter of a position;
  • protecting individual assets and equipment;
  • establishing a combined engineer obstacle line.
SYSTEM EFFECTIVENESS IS VALIDATED THROUGH TESTING
  • The following parameters are evaluated during testing:

  • stable movement of the continuous-loop cable;
  • the ability of the hooks to capture the fiber-optic cable;
  • passage of the fiber-optic cable through intermediate sections;
  • mechanical disruption of the fiber-optic line;
  • drive-system reliability under load;
  • operation across different types of terrain;
  • system response time;
  • resistance to adverse weather conditions.
