With the continuous development of unmanned aerial vehicle(UAV)technology,its applications in various fields are becoming increasingly widespread.Particularly in the field of e-mergency communications,UAVs carrying communication equipment can quickly and flexibly es-tablish communication networks,achieve air-to-ground signal coverage,and provide communica-tion support for disaster relief operations.When a disaster occurs,terrestrial communication infra-structure may be damaged.Especially in the"disconnection,power outage,and network disrup-tion"tri-disruption scenario,traditional emergency communication base stations cannot reach the disaster site in the first time to provide communication and rescue support for the affected area.However,UAVs can carry 4G/5G base stations,non-line-of-sight Mesh and other equipment,and establish transmission channels through high-throughput satellites such as ChinaSat-16,China-Sat-26,and APSTAR-6D,to quickly carry out air communication networking,and provide wide-coverage and high-capacity communication services for the rescue area,ensuring smooth informa-tion between rescuers,the command center,and the affected people,and improving the efficiency of rescue and the accuracy of command decision-making.
