Fixed surveillance and direction-finding equipment

This is a radio detection device designed for early warning, identification, and tracking of drones. It acquires the position of drone targets through protocol analysis, radio frequency signature matching, and amplitude comparison direction finding. For DJI series drones using O2, O3, and O4 data protocols, as well as some drones with public protocols, protocol analysis-based positioning can be achieved. For FPV, Wi-Fi, and assembled drones, early warning and direction finding can be performed based on radio frequency signatures. When multiple devices are networked, they can locate and track drones using TDOA or AOA positioning technologies. The device has an effective early warning detection range of over 10 km in radius (in open areas with low electromagnetic interference). It can be widely applied in low-altitude security scenarios at key locations such as airports, police facilities, petrochemical plants, power stations, industrial parks, and similar sites.
