Airborne Drone Detection and RF Geolocation System Makes World Debut at Eurosatory 2026

German manufacturer Aaronia AG officially unveiled the AARTOS Hawk T1 at the Eurosatory 2026 defence exhibition in Paris. The new system elevates electronic drone detection to the airborne domain, delivering real-time situational data through onboard passive RF geolocation technology.

Breaking the Limitations of Ground-Based Sensors

Conventional counter-UAS operations typically rely on fixed ground sensors monitoring airspace from static elevated positions. The Hawk T1 introduces an entirely new aerial vantage point configuration. Weighing under five kilograms, the system integrates directly onto commercial multirotor or fixed-wing drone platforms, enabling operators to maintain tactical visibility and effective signal capture even when complex terrain obstructs ground-based installations.

Core Technical Architecture

The Hawk T1 is built around the SPECTRAN V6 real-time spectrum analyser and employs Blind Time Difference of Arrival (Blind TDOA) technology for threat geolocation. The system can precisely locate signals from drone operators, first-person view (FPV) links, LoRa ground stations, GPS spoofing devices, jammers, and radars. It is also capable of tracking unknown, encrypted, or previously unclassified signals, with geolocation accuracy reaching up to 25×25 metres.

An onboard processing unit performs signal analysis in GPS-degraded or jammed environments, with timing synchronisation provided via multi-band GNSS. An oven-controlled crystal oscillator (OCXO) and a coherent chip-scale atomic clock (CSAC) are available as optional reference sources.

Frequency Coverage and Detection Performance

The system's standard frequency coverage spans 10 MHz to 8 GHz (civil and military bands), with optional extension down to 9 kHz and up to 18 GHz. Real-time bandwidth reaches 245 MHz, with a scanning speed of up to 1,100 GHz/second.

Field test results demonstrate:

• A network of three payload units can geolocate a LoRa drone ground station at distances of up to 75 kilometres
• In single-unit deployments, overall signal detection range can exceed 80 kilometres

Software Ecosystem and Global Deployment

The system's software architecture is powered by the RTSA-Suite PRO analytics platform, which integrates seamlessly with existing counter-UAS networks. The broader ecosystem is currently deployed at over 700 permanent installations worldwide, protecting major international hubs including London Heathrow Airport, Singapore Changi Airport, and Muscat International Airport in Oman. The wider platform has also been deployed in mobile configurations to support security operations at high-profile international events including the G20 Summit in Rio de Janeiro and the NATO Summit in The Hague.

Official Statement

Stephan Kraschansky, Chief Defence and Government Solutions Officer at Aaronia AG, commented: "Drones are becoming smaller, faster, and tactically more sophisticated. Addressing this challenge requires systems that are as adaptive as the threats themselves. With the Hawk T1, we are extending the AARTOS common operating picture into the air for the first time, creating a new quality of situational awareness that no ground-based system can match."
