基于低轨小卫星星座的搜寻定位应用

Application of Search and Location Based on Low Earth Orbit Satellite Constellation

基于低轨小卫星星座的搜寻定位和宽带通信技术具备通信延时短、路径损耗小和抗毁能力强等优势,可用于战场联合搜救。设计了一种基于低轨小卫星星座的联合搜救信息系统体系架构。该系统具备了搜寻定位、任务规划、组织协调和综合作业等能力,贯通了搜救指挥机构、遇险对象和协同搜救力量间的通信链路,满足了战场联合搜救等任务需要。

The technology of search positioning and broadband communication based on the low orbit small satellite constellation has the advantages of communication delay period,small path loss and strong anti-damage ability,thus can be used for the joint battlefield search and rescue.The architecture of joint search and rescue information system based on the low orbit small satellite constellation is proposed.This system has the capabilities of the search and location,the mission planning,the organization and coordination,and the comprehensive operations.It connects the communication links between the search and rescue command organs,the objects in distress and the cooperative search and rescue forces,and meets the mission needs of the joint battlefield search and rescue.
