摘要
对火星-地球中继通信链路特性进行研究,针对火星着陆探测器到火星轨道器以及火星轨道器到地球地面站之间两段通信链路的不同特性进行分段分析,提出火星-地球中继通信链路预算分析方法,为火星-地球中继通信系统的规划提供参考。
This paper studies on the characteristics of the Mars-earth relay communication link.The different characteristics of Mars lander-orbiter and Mars orbiter-earth station communication links are analyzed.And a Mars-earth relay communication link budget method is proposed,which offers a reference for the design of Mars-earth relay communication system.
