The TETRON® ground-based unmanned aerial vehicle (UAV) is a system that enables a rotorcraft UAV to carry out its mission when tethered by a cable to a compact ground station.

Depending on the size of the selected UAV, TETRON® can be integrated with land and marine vehicles with limited volume, can be used when vehicles are on the move, and can be used in narrow spaces. In this system, which can be integrated with various rotorcraft UAVs, depending on needs, as power is transmitted to the UAV through a cable, endurance is not limited to the UAV’s battery. Communication also takes place through the cable, preventing jamming and interception. The safety ensured by tethering the UAV to ground via a cable makes it easier to gain permission from civil aviation authorities for use in civil and controlled airspace.

The winch system developed for TETRON® can automatically and safely adjust the length of the cable to the UAV’s movements. This mechanism, which is the most critical component in such systems, has been developed based on our extensive experience in the field of ground-tethered balloon systems, and has proven itself in the field.

TETRON® is interoperable with the OTONOM GCS ground station, which is incorporated with various features, including integrated platform control, monitoring of platform status information, generation and display of operator warnings, integrated payload control, map support and recording.
Riot Monitoring

Provides decision-makers with situational awareness from a bird’s-eye perspective by flying over crowds for long durations and in a safe manner.

Disaster and Emergency Management

In the event of disasters or other emergencies, can be made mission-ready in a short time to meet various needs, ranging from surveillance to communication.

Reconnaissance, Surveillance and Intelligence

Can carry out its mission both onsite or from a vehicle, either as fixed or mobile; acts like your eyes-in-the-sky by providing uninterrupted reconnaissance, surveillance and intelligence support.

Land Traffic Management

Easily portable, enabling the aerial monitoring of land traffic in the region, allowing the necessary measures to be taken in a timely manner.

Environment Protection

Allows the detection and monitoring of fires and other environmental incidents by carrying out surveillance over a large area, and acts as the response teams’ eye-in-the-sky.


In cases where the coverage area or communication infrastructure is insufficient, can easily be deployed to the region and can expand the coverage area by carrying its payloads to high altitudes, and can ensure direct communication between assigned units over a broad area.
