基于低轨道卫星中继的无人机数据链路方案

Date Link Scheme of UAS Base on Technologies of Low Earth Orbit Satellite

基于低轨道卫星通信技术,针对高空长航时无人机系统,建立以卫星中继的通信数据链模型。从传统数据链入手,分析其存在的弊端和使用的局限性,并融合现代通信技术,在引用新型编码技术的基础上,给出了新的无人机通信数据链路方案。该设计方案以无人机作战使用实际为基础,极大地提高信息传输能力和信息安全性。

Based on the technologies of low earth orbit(LEO) satellite communication,the date link model of satellite communications is presented for the high attitude and long time unmanned aircraft system(UAS).The limitation of the conventional date link is analyzed and the advanced communication technique is be used in the paper.The date link scheme of UAS is given via using the advanced coding technologies.On the condition of the UAS operation,the ability of information transmission and security of date link sche...
