Functional characteristics

S90A Fixed UAV Detection System

The S90A Fixed UAV Detector is a professional fixed-site drone detection and positioning system designed for long-range, continuous monitoring of low-altitude airspace.
Using wideband RF spectrum detection combined with UAV positioning technology, the system can detect and identify unauthorized drones within a 1–5 km range.

The S90A supports standalone operation and is also designed for system-level integration, serving as a core sensing unit in comprehensive counter-UAV defense solutions.

Key Features

Working Principle

The S90A continuously monitors the RF spectrum to detect communication signals emitted by UAVs.
Through advanced spectrum analysis and positioning algorithms, the system identifies drone types and determines their location, providing real-time target information for early warning and coordinated defense systems.

When integrated with external countermeasure devices such as radar, electro-optical sensors, RF jammers, or spoofing systems, the S90A serves as a key detection node within a complete anti-drone defense architecture.
