  •     1月23日,我國首顆高通量通信衛星實踐十三號在軌交付,正式投入使用。實踐十三號衛星投入使用后,將被納入“中星”系列,命名為“中星十六號”衛星。

        實踐十三號衛星于2017年4月12日在西昌衛星發射中心成功發射,是我國自主研發的新一代高軌技術試驗衛星,它突破了制約我國航天技術跨越發展的諸多瓶頸技術,為“航天強國”“寬帶中國”建設提供了有力支撐。實踐十三號實現了Ka頻段寬帶技術在我國通信衛星上的首次應用,通信總容量達20Gbps,標志著我國衛星通信進入高通量時代。2017年,該衛星成功進行了國際首次高軌衛星對地高速激光雙向通信試驗,標志著我國在空間高速信息傳輸領域走在了世界前列,成為國際上首個掌握該技術的國家。同時,這是我國首次在高軌長壽命通信衛星上工程化應用地球敏感器、Ka頻段寬帶接收機等國產化產品,實現了衛星關鍵核心單機的自主可控,并使我國首次實現在衛星上配置電推進分系統來完成全壽命期的軌道位置定點工作,推動我國衛星平臺技術全面跨入電推進時代。

        實踐十三號衛星主要為中國地區等區域用戶提供服務,可實現偏遠地區的移動通信基站接入及其他行業應用,廣泛應用于企業專網、遠程教育、醫療、互聯網接入、數字新聞采集、機載船舶通信和應急通信等領域。該星可方便用戶快速接入網絡,能滿足航空、航運、鐵路互聯網用戶接入需求。相比傳統C、Ku頻段通信衛星,實踐十三號衛星終端設備更小、易于使用,以流量計費的商業模式比傳統頻段衛星的模式更顯靈活。此外,實踐十三號衛星還具有快速部署、建設周期短等優勢。

        據了解,后續我國還將部署超大容量高通量衛星,預計到2020年形成可覆蓋中國全境以及亞太地區、容量接近200Gbps的通信能力,有力滿足“寬帶中國”和國家“一帶一路”建設工作對寬帶通信的迫切需求。
