Modular Multi-sensor Counter-UAV System Protected Football Stadium in Gdynia Against Drones during UEFA EURO U21 Football Matches 16-30 June 2017

SafeSky, produced by Advanced Protection Systems Sp. z o.o. is a unique, multi-sensor drone detection and tracking system that allows effective detection and neutralization of drones day and night in any weather conditions without blind zones providing true dome/umbrella like protection. A combination of proprietary radar, acoustic, vision and RF sensors enables minimized alarm rates detection of small drones at a distance of at least 1000 m.

SafeSky has been recently deployed to protect UEFA EURO U21 football stadium in Gdynia against malevolent use of drones. It also already protects other installations as prisons, hotels, private properties, manufacturing companies and some governmental installations.

What makes SafeSky unique is a combination of four different sensors based on proprietary technologies and developed specifically to detect and identify drones.

Radars, being the primary sensor, are based on proprietary space technology - developed within numerous projects of the company with European Space Agency. Furthermore, radar sensors are miniaturized and low power, while intelligent signal processing allows to differentiate drones from birds for minimized alarm rates.

Acoustic array conducts beam forming in space detecting direction of sound sources. Special machine learning algorithms allow to identify drones from among other potential sound sources, ignoring background noise.

Vision camera employs dedicated image processing algorithms that detect, identify and track drones. Radars allow to point the PTZ camera into the right portion of space so that visual domain identification is possible and effective.

RF sensor captures transmissions between the drone and its operator. It allows to identify drone type. If a number of RF sensors is deployed in a given site, drone operator can be localized and his/her position indicated.

All SafeSky sensors data is fused and result is presented in an integrated software environment. No drone zones are easily defined. Alarms are issued via sms, email and in graphical and sound form when drone approaches protected zone. SafeSky application is web based and can be run both on desktop computers and tablets for untethered operation.

On the neutralization side, SafeSky employs a layered approach. Brute force directive jammers are employed and/or drone hacking. Which countermeasures are used depends primarily on the legal context - jammers cannot be legally used in many places. Applied countermeasures force drone to return to its operator or make drone land safely in a controlled manner.

SafeSky is modular and scalable. A different configuration of sensors can be applied, either on a single mast for stationary deployment or on a tripod for increased mobility. Radars come in different form, with different coverage angles, output powers and operating frequencies to optimally serve different clients. If a really large area needs to be protected, e.g an airport, a number of SafeSky units can be easily connected - it is a scalable design.
