TDOA+AOA Network Locks DJI & Autel Drone Positions

Most also have limited frequency coverage, missing modified drones operating on less common bands. For wide-area protection zones, there is growing demand for detection systems that combine broad coverage with precise positioning — delivering full-area situational awareness through grid deployment and providing accurate coordinate data for subsequent countermeasure operations.

Built with an ultra-wideband passive receiving architecture, the device covers a full detection frequency range of 100MHz to 6GHz (Evidence: Product Specification Document). It identifies mainstream brand drones including DJI, Autel, Fimi, Dahua and Yuneec, plus FPV racing drones, Wi-Fi drones and most other models on the market — supporting over 500 model variants in total.

A single unit performs independent target direction finding with ≥3km DF range and approximately 10° accuracy, displaying real-time drone bearing on electronic maps. When multiple units are deployed in a grid configuration, fused calculation via TDOA (Time Difference of Arrival) algorithms delivers positioning accuracy within 20 meters (Evidence: Product Specification Document), outputting precise coordinates for both drones and pilots to support law enforcement operations.
The system supports trajectory playback and historical detection record queries, retaining multi-dimensional information including drone serial numbers, models and frequency bands to form a complete electronic evidence chain.

Using passive detection technology, the device emits no electromagnetic signals at all, creating no electromagnetic pollution — ideal for deployment in complex urban electromagnetic environments. Total power consumption is ≤50W (Evidence: Product Specification Document) with dual AC 220V and DC 12V power support. Rated IP65 with an operating temperature range of -40°C to 65°C, it runs uninterrupted 24/7 through rain, snow, high heat and extreme cold.
It supports detection-to-countermeasure linkage, automatically triggering jamming systems when targets are detected. A standard API interface enables integration with third-party management platforms for flexible incorporation into existing security systems.

This TDOA+AOA hybrid positioning drone detection system combines three core advantages — ultra-wideband full-model recognition, 20m multi-station networked positioning and passive all-weather operation — and is compatible with all DJI, Autel and FPV drone categories. Single stations operate independently for direction finding, while networked multi-unit deployments build full-area precision defense systems, serving as standardized low-altitude sensing equipment for airports, prisons, energy facilities and large events.
