簡介：在地震、海嘯、山洪等自然災(zāi)害發(fā)生的時(shí)候，地面基站常常會(huì)被毀壞，災(zāi)害地區(qū)的通信基礎(chǔ)設(shè)施損壞不能提供通信服務(wù)，這使得救援行動(dòng)的開展受到較大的阻礙。無人機(jī)基站不受災(zāi)害地區(qū)基礎(chǔ)通信設(shè)施的限制可快速為災(zāi)害地區(qū)提供大范圍的可靠通信。
Introduction: When natural disasters such as earthquakes, tsunamis, and flash floods occur, ground base stations are often destroyed, and the communication infrastructure in disaster areas is damaged and unable to provide communication services, which greatly hinders the implementation of rescue operations. Unmanned aerial vehicle base stations are not limited by the basic communication facilities in disaster areas and can quickly provide reliable communication on a large scale for disaster areas.

無人機(jī)基站不受災(zāi)害地區(qū)基礎(chǔ)通信設(shè)施的限制，可以以主從無人機(jī)方式快速為災(zāi)害地區(qū)提供大范圍的可靠通信，其中主無人機(jī)是固定的空中基站可以為應(yīng)急通信控制中心提供可靠通信覆蓋。
以主無人機(jī)為中心用圓形軌跡飛行的空中基站，為邊緣用戶提供通信覆蓋。無人機(jī)可以分為固定翼和旋轉(zhuǎn)翼無人機(jī)，固定翼無人機(jī)能夠保持在空中的持續(xù)飛行，旋轉(zhuǎn)翼無人機(jī)可以在空中懸停。
The drone base station is not limited by the basic communication facilities in disaster areas, and can quickly provide reliable communication over a large range in the form of master-slave drones. The master-slave drone is a fixed aerial base station that can provide reliable communication coverage for the emergency communication control center.
An aerial base station flying in a circular trajectory centered around the main drone, providing communication coverage for edge users. Drones can be divided into fixed wing and rotary wing drones. Fixed wing drones can maintain continuous flight in the air, while rotary wing drones can hover in the air.
無人機(jī)中繼通信中，任務(wù)無人機(jī)和中繼無人機(jī)之間的信道以及中繼無人機(jī)和地面控制終端間的信道存在差異。
無人機(jī)之前的數(shù)據(jù)鏈路分為上行鏈路和下行鏈路。上行鏈路為遙控鏈路，即將地面控制終端的指令信息發(fā)送給無人機(jī)；下行鏈路為遙測鏈路，即將無人機(jī)上的遙測信息傳遞給地面控制站。
In drone relay communication, there are differences in the channels between task drones and relay drones, as well as between relay drones and ground control terminals.
The data link before the drone was divided into uplink and downlink. The uplink is a remote control link, which sends command information from the ground control terminal to the drone; The downlink is a telemetry link, which transmits telemetry information from the drone to the ground control station.
無人機(jī)作為移動(dòng)中繼可以根據(jù)任務(wù)部署，成本效益高，移動(dòng)性好，并且比起傳統(tǒng)的固定中繼具有靈活的 3D 位置，飛行軌跡等更多的可優(yōu)化維度，可以提高通信性能。
As a mobile relay, drones can be deployed according to tasks, with high cost-effectiveness, good mobility, and more optimized dimensions such as flexible 3D positions and flight trajectories compared to traditional fixed relays, which can improve communication performance.
