摘要
本文介绍了在“双星”系统的中继星上增加一个２．５ｍ直径Ｓ波段跟踪天线和２个转发器，与地面站一起构成初级ＴＤＲＳＳ系统。可以提供对飞船跟踪与通信的７０％以上的轨道覆盖率和２Ｍｂｐｓ的反向数传速率，解决了只依靠大量地面布站所面临的许多困难。
Abstract：The elementary track and data relay satellite system（TDRSS） can be realized by use of the data relay satellite of″Dual Satellites″system in which a S—band 2m diametertrack antenna and 2 transponders are increased and correspondent TDRSS ground station. Itcan provide above 70％ orbit cover ratio for tracking airship and communicatio and 2Mbpsdata transmission rate with it．The many difficulty that resulted from a big amount of station be built on ground may be resolved.
