摘　　要：利用无人机(天)、千兆非视距微波传输系统(地)资源,实现空天地联合的新一代应急通信系统。打通高通量卫星传输链路,通过将Ka高通量卫星与LTE基站相融合快速恢复受灾现场4G网络。创新性地将系留式无人机与传统地面MESH网络相结合,通过无人机搭载MESH中继设备,快速搭建远距离无线通信网络,极大提升远端MESH单兵设备与近端MESH基站设备间的通信距离。通过非视距微波传输技术,实现遮挡严重场景4/5G站点应急开通。By utilizing UAV(air)and gigabit non-line-of-sight microwave transmission system(ground)resources,a new generation of emergency communication system integrating air,space,and ground capabilities can be achieved.A high-throughput satellite transmission link is established to quickly restore the 4G network at the disaster site by integrating the Ka high-throughput satellite with LTE base stations.The tethered UAV is innovatively combined with the traditional ground MESH network,and the MESH relay device is equipped with the UAV to quickly build a long-distance wireless communication network,greatly improving the communication distance between the remote MESH individual equipment and the near-end MESH base station equipment.Through non-line-of-sight microwave transmission technology,the emergency opening of 4/5G stations in severe occlusion scenarios is realized.
