摘要
目前广东省消防的卫星通信系统主要使用Ku频段的卫星,而Ku频段卫星频率资源缺乏,卫星链路带宽低,在灾害发生时,后方指挥部和指挥中心能从前方指挥部获取的信息量十分有限,没有多余的带宽提供给前线其他应急通信设备使用。本文分析了当前消防卫星系统所存在的问题和需求,提出使用高通量Ka频段卫星通信系统,满足当前消防应急救援通信需求。
At present,Ku-band satellites are mainly adopted in fire protection in Guangdong province.However,the frequency resources of Ku-band satellite are tight and the link bandwidth is low.Therefore,when the disaster occurs,the information that the rear command and command center can obtain from the front is very limited,and there is no extra bandwidth for other emergency communication equipment on the front line.The problems and requirements of the current firefighting satellite system are analyzed,and the high-throughput Ka-band satellite communication system is proposed to put on use,which can effectively solve the problem of low bandwidth and limited transmission of information resources in the current firefighting satellite system.
