High speed data transmission technology is one of the key technologies applied in the second generation of data relaying satellite system and other military communication systems 高速数据传输技术是应用于第二代数据中继卫星系统和其它军事卫星通信系统的关键技术之一。
Drss ( data relay satellite system ) is one of the main projects of our country in recent years , among which the high - speed data communication technology is one of the key points 数字中继卫星( drss )是我国近年来发展的重点项目之一,而高速数据传输技术又是其中的关键技术。
And it precisely described the fundamental working principle of a relay satellite antenna capturing and tracking system as well as the factors could affect the working performance 论文详细论述了中继卫星天线捕获跟踪系统的基本工作原理和影响因素,系统地综述了相关技术发展现状。
The inter - satellite link ( isl ) establishing is the precondition for tdrs system ’ s operation . acquisition and tracking ( a & t ) technology is one of the key technologies for isl establishing 星间链路的建立是中继卫星系统运行的前提,星间链路捕获跟踪技术是星间链路建立技术中的关键。
And the limitation and tracking precision demands of 2nd generation ctdrss are also analyzed . the course and theory of ctdrss ’ s isl establishing are studied , and the structure of isl a & t system is given 分析了中继卫星系统星间链路建立的过程和原理,给出了星间链路捕获跟踪系统的结构。
Tracking and data relay satellite ( tdrs ) system is a communication system providing continous and real - time services such as tracking , telemetry , command and data relay for low - earth - orbit spacecraft 中继卫星系统是一个为低轨航天器提供连续、实时的跟踪、测控与数据中继服务的卫星通信系统。
As a novel space - based tracking , telemetering and command system , the tracking and data relay satellite system ( tdrss ) represents a new direction in the international tracking telemetering and command field 作为一种新型的天基测控系统,跟踪与数据中继卫星系统( tdrss )代表了国际上测控领域的新的发展方向。
The inter - link of tdrss contained forward link and return link . the forward link is the signal retransmitted from earth station to relay satellite , then transmitted the tt & c to the user aircraft 前向链路指地面站经数据中继卫星转发信号,向用户航天器(包括成像侦察卫星、航天飞机与载人飞船等)发送跟踪、遥测与控制指令。
The achievements of research on isl a & t are not only used in tdrs systems , but also other wireless link between spacecrafts . the simulation system established can also be used to analyze other a & t proceedings 文章对于星间链路捕获跟踪技术研究的成果和建立的仿真系统,不只能用于中继卫星系统,也可拓展到其他飞行器无线连路的建立。
