drone detection and neutralization system

Ctrl+Sky is a multi-sensor counter-drone system that is able to detect, track and neutralize intrusive drones. It is exceptionally effective because it is based on proprietary, patented technology and multi-sensor approach: from software to hardware.

how it works?

Thanks to the multi-sensor approach, Ctrl+Sky enables efficient detection, identification and neutralization of drones, day and night, in all weather conditions. Ctrl+Sky offers a scalable system approach to ensure a complete “dome” of protection from unwanted drone invasion.

system operation


The combination of patented radar, acoustic, vision and RF sensors allows Ctrl+Sky to minimise false alarms and detect even small drones at distances up to 2000 meters.

The FMCW radar sensor operates in the X band and uses MIMO technology to locate drones. Ctrl+Sky uses the most advanced radar tracker based on MHT algorithm. The system can distinguish drones from other flying objects, such as birds.


The acoustic sensor is based on 8-element microphone array that uses digital beamforming technique to accurately localize sound sources in 3D space. Advanced, machine learning based classification algorithms discriminate between drones and other objects.

Video cameras register recordings of detected drones, so it is possible to present hard evidence of an intruder in a protected area.


The RF Sensor detects radio-link between a drone and remote control-station by identifying radio frequency (RF) signatures of Wi-Fi signals. The RF sensor detects a targeted radio signal, identifies it and with Ctrl+Sky software allows neutralization of unwanted drones. By using multiple RF Sensors the drone operator can also be localized.

Ctrl+Sky Jammer is an optional element of the system. Jammer is used to neutralize drones by overpowering drone’s receivers. Its use is restricted to a group of customers with appropriate permissions.
