摘要
近距链路是小范围、双向、固定或移动的无线通信链路,一般应用于无人探测器、着陆器、行星探测器及静止轨道舱之间的相互通信。文章介绍了近距空间链路协议的原理及特性,讨论了近距链路协议的层结构和传输单元(PLTU)的构成,分析了Proxim ity-1(近距空间链路协议)的业务类型,并对近距链路协议的应用进行了展望。
Proximity-space link is short-range, bi-directional, fixed or mobile radio links which are generally used to communicate among probes, landers, rovers, orbiting constellations, and orbiting relays. The principle and characteristics of Proximity-space link protocol are introduced in this paper. The composing of PLTU and layer structures are discussed and service types of Proximity-space link protocol is analyzed, and the application on Proximity-space link protocol is prospected.
