中继卫星系统的天基测控通信是近代航天技术的重大突破,它能够有效地满足航天器交会对接的测控通信需要。文章分析了美国"跟踪与数据中继卫星系统"(TDRSS)和欧洲"阿特米斯"(ARTEMIS)中继卫星对"自动转移飞行器"(ATV)与"国际空间站"(ISS)交会对接任务的测控通信支持,总结了国外中继卫星系统支持航天器交会对接任务的4个特点:①构建以中继卫星系统为主的天地一体化测控通信网;②推荐使用TDRS卫星单址天线支持同一波束内2个目标的测控通信;③中继终端采用多副S频段天线实现测控通信的连续覆盖;④在加强国际合作的同时大力发展自己的中继卫星系统。研究表明,以中继卫星系统为主的天地一体化测控通信网,可以解决当前陆海基测控网所面临的覆盖率低、运行成本高等难题,能为航天器交会对接任务提供有力的测控通信保障。

Space-based TTC technology using data relay satellite system is a great breakthrough in modern space technology domain,and can effectively meet the TTC and communication requirements of spacecraft rendezvous and docking mission.This paper analyzes TTC and communication supports provided by tracking and data relay satellite system(TDRSS) and ARTEMIS for Automated Transfer Vehicle(ATV)/International Space Station(ISS) mission,and summarizes four features of supporting spacecraft rendezvous and docking mission by TDRSS,ARTEMIS,etc.: ①An integrated space and ground-based TTC and communication network dominated by data relay satellites system is built;②Using the single access(SA) antenna onboard TDRS spacecraft to support two user platforms within the same SA antenna beam is encouraged;③The user terminals use multiple S-band antennas to implement the continuous TTC and communication coverage;④Many nations make an effort to develop their own data relay satellite systems while enhancing the cooperation with each other.The study results show that an integrated space and ground-based TTC and communication network dominated by data relay satellites system can overcome the difficulties such as low coverage,high operational cost faced by the ground and sea-based systems,and therefore can provide the better TTC and communication supports for spacecraft rendezvous and docking mission.
