简介：在地震、海啸、山洪等自然灾害发生的时候，地面基站常常会被毁坏，灾害地区的通信基础设施损坏不能提供通信服务，这使得救援行动的开展受到较大的阻碍。无人机基站不受灾害地区基础通信设施的限制可快速为灾害地区提供大范围的可靠通信。

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.

无人机基站不受灾害地区基础通信设施的限制，可以以主从无人机方式快速为灾害地区提供大范围的可靠通信，其中主无人机是固定的空中基站可以为应急通信控制中心提供可靠通信覆盖。

以主无人机为中心用圆形轨迹飞行的空中基站，为边缘用户提供通信覆盖。无人机可以分为固定翼和旋转翼无人机，固定翼无人机能够保持在空中的持续飞行，旋转翼无人机可以在空中悬停。

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.

无人机中继通信中，任务无人机和中继无人机之间的信道以及中继无人机和地面控制终端间的信道存在差异。

无人机之前的数据链路分为上行链路和下行链路。上行链路为遥控链路，即将地面控制终端的指令信息发送给无人机；下行链路为遥测链路，即将无人机上的遥测信息传递给地面控制站。

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.

无人机作为移动中继可以根据任务部署，成本效益高，移动性好，并且比起传统的固定中继具有灵活的 3D 位置，飞行轨迹等更多的可优化维度，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.

用户应根据自身实际情况出发，选购一款或多款产品搭配使用。多旋翼临时基站、多旋翼长时间滞留基站、固定翼空中基站等。

选择保障当下应急救援通信，还是恢复周边范围内民用通讯，得视情况而定。当然，如果设备资源充足条件下，可同时进行，从而全方位实施通信救援。

Users should choose one or more products to use in combination based on their actual situation. Temporary multi rotor base stations, multi rotor long-term stranded base stations, fixed wing aerial base stations, etc.

The choice between ensuring current emergency rescue communication or restoring civilian communication within the surrounding area depends on the situation. Of course, if the equipment resources are sufficient, it can be carried out simultaneously to implement communication rescue.
