Product Introduction

       This high-performance DJI & RID integrated decoding module is a dedicated RF sensing hardware for low-altitude UAV defense systems, built with FPGA signal processing architecture and 61.44MHz sampling rate to deliver top-tier DJI drone capture capability.
It fully decodes unencrypted DJI O3 series signals, directly outputting drone coordinates, pilot location, home point, serial number, drone model, altitude and flight speed. For the latest encrypted DJI O4 drones (Mini4, Air3s, Avata2, Mavic4 Pro), the module outputs complete 176-byte encrypted raw data, which can be fully decrypted via our dedicated server to retrieve full flight & identity information.
       Compliant with international and domestic drone remote identification standards ASTM F3411-22a & GB42590-2023, it independently captures broadcast RID signals with 1–5km detection distance. All signal analysis and decoding processes run locally on the module without external computing equipment. Compact low-power design supports seamless integration into fixed-site monitoring stations, vehicle-mounted anti-drone equipment and portable detection terminals, with data output via UDP/TCP Ethernet or 3.3V TTL serial port for easy secondary development.

Key Features

1、FPGA high-speed processing, 61.44MHz sampling rate, industry-leading DJI signal decoding performance
2、Full DJI protocol compatibility: O3 unencrypted & O4 encrypted drone signal capture
