Satellite fusion unmanned aerial vehicle carried 4G communication base station air-to-ground networking system

Abstract

The invention discloses a satellite fusion unmanned aerial vehicle carried 4G communication base station air-to-ground networking system, which comprises 4G communication base station equipment integrated on an unmanned aerial vehicle platform, a sight distance link airborne terminal, a Ka satellite communication airborne terminal, a ground control station and a gateway station. The Ka satellite communication airborne terminal and the gateway station form a Ka satellite communication link through the low-orbit broadband communication satellite, and the 4G communication base station equipment and the line-of-sight link airborne terminal are both connected with the Ka satellite communication airborne terminal. The system provided by the invention can provide networking service with lower delay and larger bandwidth by utilizing the 4G communication technology and the Ka high-throughput satellite communication system, and supports access of more ground terminal users.

Description

technical field [0001] The invention belongs to the technical field of emergency communication, and in particular relates to an air-to-ground networking system equipped with a 4G communication base station on a satellite fusion UAV. Background technique [0002] At present, the traditional domestic communication emergency network support methods mainly include emergency communication support vehicles, satellite communication systems and tethered UAV base stations, but there are emergency communication vehicles that cannot be reached in a short time due to traffic and roads; satellite communication exists Problems such as low terminal popularity, poor signal, large delay, and high tariffs; tethered UAV low-altitude stations have limitations such as short flight time, small load, small coverage area, and short power supply time. The large and medium-sized UAV communication relay system developed in recent years is based on 4G base stations and Ku satellite communication data l...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned deficiencies in the prior art, the air-to-ground networking system provided by the invention provides a satellite fusion UAV equipped with a 4G communication base station, which solves the problem that the number of supported ground user terminals is not high.
