Ukrainian counter-uncrewed aerial systems developer Kara Dag Technologies currently has an investment round open with a “limited portion” still available. The company manufactures dual use drone detectors for civilian use which have also been deployed on the battlefields in Ukraine. Systems can be supplied to protect infrastructure and the company also provides drone detection as a service for municipalities and police forces.
The range includes the Obriy 1.3 drone detector, a wearable device that is designed to detect the approach and direction of DJI-type and FPV drones from 2.5 to 4 km away. It continuously scans 1.2GHz, 2.4GHz, and 5.8GHz bands to identify the presence of drone signals while filtering out interference using a proprietary software algorithm. Kara Dag says the device has undergone successful field testing, is mass-produced, and receives regular software updates. Features include a direction finding mode, close detection mode and a battery life of up to eight hours.
The company is also currently developing the Obriy 2.0 drone detector. It is designed to detect UAS and interference sources by their radio frequency signatures using a proprietary AI model, trained on Kara Dag’s database of drone signatures. The networked detectors can share information with each other using ultra-low-power transmitters. They also include basic drone protection systems based on pre-recorded proprietary signals.
With the operator’s consent, the detectors regularly submit newly captured signatures to the R&D center, assisting in building a comprehensive drone RF signature database. “This is the very basis for the business model, which is based on selling subscriptions for regular AI model updates, trained on the most recent UAS signatures gathered worldwide,” the company says.
In addition, a stationary version, Obriy S, is also under development. Adapted for installation on buildings, vehicles, or masts, networks of Obriy S could be used to defend critical infrastructure, including airports, factories, and power plants from rogue drones, as well as monitoring compliance with UAS regulations.
The Stribog is the company’s third device currently under development. Kara Dag describes it as an “ultra-light autonomous (under 0.5 kg) signal intelligence system that can be installed on an FPV drone to guide it toward signal sources” such as those operating drones carelessly or with malintent.
