Background
In conventional unmanned aerial vehicle beyond-the-horizon data link communications, only a single link is typically employed, based on a satellite communications network. The single link scheme has a certain risk, and communication interruption can occur in the process of executing the task by the unmanned aerial vehicle, so that the completion of the task is influenced. The stability and reliability of the communication link is critical to the normal operation of the drone. Conventional communication satellites may fail during operation, such as a failed launch, an abnormal orbit, a system failure, etc., resulting in an interruption of the communication link. In addition, satellite communications are susceptible to electromagnetic interference and natural environment interference, such as thunderstorms, solar flares, etc., which in turn affect the stability of the communications link. Problems with ground satellite communication stations, antenna alignment bias, hardware equipment damage, etc., may result in communication link interruption or degradation. Meanwhile, in the flight process of the unmanned aerial vehicle, shielding factors such as terrain, buildings and the like can be encountered, so that the satellite communication link is temporarily interrupted. Satellite communication links may also be subject to hacking or malicious interference, resulting in interruption of communications or leakage of sensitive information. Due to the above problems, it is important to use redundant links to ensure that the unmanned aerial vehicle has a stable and reliable communication link in the task execution process. However, the conventional redundancy link scheme may have problems of limited coverage, high cost, and the like.
