无人机系统的卫星中继数据链

针对大中型无人机系统实现远程测控与信息传输的技术需求,在参考国外＂捕食者＂、＂全球鹰＂等先进无人机系统技术体制和实现方案的基础上,提出了利用商业或军用通信卫星作为空中中继平台,建立无人机卫星中继数据链,实现我国远程无人机系统的超视距遥控、遥测和侦察信息实时传输的解决方案,这对延伸无人机系统的作用距离、提高作战效能具有重要意义。文中分析了无人机系统卫星中继数据链的技术体制,提出了工程应用中的关键技术,对具体的工程实现具有一定的指导意义。

Satellite Relay Data Link for UAVs

Following a study of the requirements of large and medium-sized UAV （Unmanned Aerial Vehicles） sys-tems and the technical system and designs of Predator and Global Hawk UAVs, this paper proposes establishment of a satellite relay data link for UAVs through commercial or military satellites for reahime over-the-horizon trans-mission of command, telemetry and reconnaissance information for long-range UAVs. The satellite relay data link is of high significance by extending the operational range and enhancing combat effectiveness of UAVs. The technology system of a satellite relay data link for UAVs is analyzed and key technologies are pointed out. The approach pro vides valuable reference to engineering practices.
