第三代中继终端、测控通信保障中国航天员舱外通信

重庆长寿区可以找姑娘的地方,【+Q:★2ЗЗ⒏412⒉★】姑·娘·全·天·安·排-18-至40岁任挑【+Q:★2ЗЗ⒏412⒉★】祝您开心不指一次√√√  从上个世纪80年代开始,三星堆遗址逐渐影响和改变了这片土地。陈德安和同事们的眼光,也并不只在坑里的文物,而是要探究几千年前的城池布局、城乡关系。

  中新网北京7月4日电 (马帅莎)中国航天员4日顺利完成中国空间站首次出舱任务。航天员出舱后如何与地面取得联系引发关注。

  出舱活动是航天员身着舱外航天服在航天器外进行太空行走和作业的统称。进行出舱活动时与地面建立高速及时的通信联系尤为重要,出舱活动不仅是对航天员的全方位考验,也是对空间站天和核心舱与地面测控站间通信能力的一大考验。

  第三代中继终端:可在轨维修

  中国航天科技集团五院研制的第三代中继终端产品,通过与中继卫星天链一号和天链二号建立中继链路,实现中继通信,确保航天员与地面通信的实时畅通。这就好比在太空中搭建了地面与中继卫星、中继卫星与航天员之间的“天路”。

  此外,空间站中继终端与其他型号在设计上最大的区别在于,为了保证在轨使用的长寿命,需要具备在轨可维修性。空间站中继终端采用了集成化、模块化的设计思路,在保证传输信号质量的同时,方便航天员维修更换。

  测控通信产品:支撑多名航天员舱外通话

  中国航天科技集团五院研制的出舱通信子系统实现舱内外航天员之间、舱内外航天员与地面人员之间以及舱外航天员之间的全双工语音通信,在航天员舱外活动范围内实现无线通信全覆盖。

  与上一代出舱通信系统相比,该产品具有通信距离更远、通信速率更高、工作寿命更长等特点,同时由于采用了功率控制、抗多径等措施,该产品具有更强的空间环境抗电磁干扰能力,并支撑多名航天员同时出舱活动时的通话功能。

  舱外图像传输子系统为舱外提供无线网络覆盖,通过出舱无线收发设备提供的“热点”进行图像传输,实现了航天员出舱活动进行实时显示,实时记录等功能以及为太阳翼绕行测量试验提供数据传输功能。(完)
