Unmanned aerial vehicle cluster beyond visual range networking device and method based on Beidou system

Abstract

The invention provides an unmanned aerial vehicle cluster over-the-horizon networking device and method based on a Beidou system. The method comprises the steps: enabling an LAN receiving channel to enter a combination switch after amplification and filtering the signal, enabling the signal to be transmitted to a receiver baseband processing unit after selection in the combination switch, enablingthe signal to pass through an RNSS / RDSS channel after the signal is received and being selected by a shunt switch, and emitting the signal after power amplification, wherein the receiver baseband processing unit is responsible for signal receiving and signal broadcasting performance of the RNSS / RDSS dual-mode receiver. According to the invention, the problem of difficulty in long-distance networking of the unmanned aerial vehicle cluster is solved, compared with the conventional radio station networking mode, the situation that the networking cannot be carried out due to long-distance weak signals is avoided, and the reliability of the unmanned aerial vehicle cluster networking is improved. Thus, the communication and navigation integration of the unmanned aerial vehicle is achieved, theequipment size is greatly reduced, the equipment weight is reduced, and the cruising ability of the unmanned aerial vehicle is effectively supported.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle communication, in particular to a device and method for cluster communication networking. Background technique [0002] The RDSS system covers a wide range, is less affected by terrain, and has low construction and maintenance costs. Compared with traditional equipment, it is more suitable for application in RDSS airborne equipment as emergency communication or backup communication equipment. [0003] The information reception and dissemination between ground-to-air, air-to-air and ground equipment mainly rely on the data link for data source transmission. UAV communication is limited by the communication distance. When the distance between different UAV clusters is long, the real-time performance and synchronization are poor, and effective link communication cannot be carried out. At present, countries around the world have developed a variety of data link systems. Among them, the Beidou s...
