Eurosatory 2026: Aaronia Unveils Hawk T1 Drone-Borne Passive Counter-UAS Detection System

Aaronia AG has officially launched the AARTOS Hawk T1 at Eurosatory 2026, extending drone detection capabilities into an entirely new dimension. According to the company, it is "the first passive RF geolocation system based on Blind-TDoA (Time Difference of Arrival) technology capable of transmitting data in real time directly from the air, enriching the ground common operational picture from perspectives that fixed ground-based systems cannot achieve alone."

Redefining the Detection Paradigm

Aaronia notes that drone detection has long been the domain of fixed or mobile ground-based systems. While reliable, such systems are inherently limited to looking upward from a fixed vantage point. The AARTOS Hawk T1 fundamentally changes this paradigm — designed as a compact RF geolocation payload that mounts directly onto commercial multirotor or fixed-wing drone platforms, bringing AARTOS detection capability to where threats actually operate: in the air.

"When terrain blocks line of sight, threats relocate rapidly, or wide-area surveillance is needed without fixed infrastructure, ground systems hit their limits. The AARTOS Hawk T1 was built to close that gap: it extends the tactical common operational picture into the third dimension, detecting RF signals within the airspace and transmitting location and classification data in real time to ground command posts."

System Specifications and Technical Features

The AARTOS Hawk T1 weighs under 5 kg and is engineered for rapid integration onto existing drone platforms. The system ships pre-configured in a ruggedized transit case with no complex field installation required — it is mission-ready straight out of the box.

At its core is the SPECTRAN® V6 real-time spectrum analyzer (the shared hardware foundation across all AARTOS systems). The system employs Blind-TDoA technology for precise geolocation of RF emitters, covering targets including:

• Drone operators
• FPV links
• LoRa ground stations
• GPS spoofers
• Jammers
• Radar signals

Blind-TDoA also enables the localization of unknown, encrypted, or previously uncatalogued signals, with geolocation accuracy down to 25 × 25 metres.

The system integrates Aaronia's proprietary high-performance computing unit, ensuring robust signal processing even in GPS-denied or jammed environments. Timing synchronization uses multi-band GNSS with PPS output, with optional OCXO and atomic clock reference (CSAC) configurations available.

Frequency Coverage and Operational Validation

The system covers 10 MHz to 8 GHz (optionally 9 kHz to 18 GHz), spanning both civilian and military frequency bands, with a real-time bandwidth (RTBW) of 245 MHz I/Q and a scan speed of up to 1,100 GHz/s.

Field deployment tests have confirmed that a network of just three Hawk T1 payload units can reliably geolocate LoRa drone ground stations at distances of up to 75 km.

The system simultaneously monitors all relevant spectrum in real time, locating both drones and their operators — with detection ranges exceeding 80 km in most operational scenarios.
