Problems solved by technology

Although the wireless data link technology in the civil and commercial fields is relatively mature, most of them are designed for the Reighly channel represented by the urban environment, and most of them are ground mobile platforms. In the telemetry and remote control data link of aviation unmanned aerial vehicles, this problem is even more prominent

In the traditional aeronautical radio data link system, it often faces problems such as insufficient anti-interference ability, lack of system robustness, and lack of derating processing capability. It is an important problem that needs to be solved urgently. For UAV telemetry remote control and communication data link systems, it is even more important to improve the reliability of UAV systems by improving broadband transmission performance, enhancing system anti-jamming capabilities and derating design capabilities.
