    首頁 - 北斗 - 千尋位置與清華大學合作為北斗地基增強系統提供升級技術
點擊:88        時間:2019-06-27 08:42:07

  6月20日,全球精準位置服務提供商千尋位置網絡有限公司(以下簡稱“千尋位置”)與清華大學電子工程系達成合作,雙方將在衛星導航信號處理技術層面展開全面合作,為北斗地基增強系統“全國一張網”的進一步完善和升級換代提供。
  根據合作框架,雙方研發團隊將就地基增強站的新一代全球導航衛星系統(GNSS)信號接收與處理、干擾與欺騙抑制等方面開展定制化的合作研究。
  清華大學科研院副院長李水清教授表示,清華大學和千尋位置的這次合作,有利于清華大學衛星導航關鍵技術成果的快速轉化和實際應用,也將進一步提升千尋位置在地基增強方面的技術水平,推動國家基礎設施的建設,促進時空信息在各行各業的廣泛應用。
  由于受到衛星軌道誤差、衛星鐘差等系統性因素影響,衛星定位的誤差難以消除。通過在地面建立地基增強站,提供差分修正信號,可以有效將衛星定位的精度提高至厘米級、甚至毫米級。千尋位置目前在全國運營超過2200個地基增強站,擁有全球最大規模的衛星地基增強系統。
  據千尋位置透露,此次雙方合作,不僅可以提高地基增強站對衛星導航信號接受和處理的能力,還可以對地基增強站GNSS接收機進行靈活配置,讓千尋位置的精準時空服務更快覆蓋所有新體制信號和新增的可用衛星。
  值得一提的是,此次合作將為包括北斗三號在內的所有GNSS公開服務信號提供先進的信號處理技術,更好支持北斗全球衛星信號。據悉,北斗三號啟用了新一代互操作信號。
  基礎技術能力的夯實,將讓千尋位置繼續領跑精準時空賽道。精準時空,就是精確的時間校準和空間定位,是5G萬物互聯時代的基礎設施,也是虛擬和現實世界融合的數據橋梁。
  千尋位置CEO陳金培表示,5G帶來的物聯網革命,讓精準時空服務加速成為各行各業的一項基本能力。千尋位置正在構建一個關于精準時空的數字生態,提高傳統產業效率,帶動新興產業規模。千尋位置將與清華大學等優質學術力量合作,不斷打磨基礎設施的技術核心,提高時空服務的可靠性和便捷性。
  2015年8月,千尋位置由阿里巴巴和中國兵器出資成立,其經營業務正是建立覆蓋全國的北斗地面增強基站系統,接收北斗衛星系統(兼容GPS、GLONASS、Galileo)的基礎定位數據,然后利用自主定位算法,通過互聯網技術進行大數據運算,提供精準定位及延展服務。
  清華大學電子工程系定位、導航與授時(PNT)中心是國內領先的衛星導航技術研究機構,在國際學術界和工業界具有重要影響力,在北斗衛星導航系統的建設和應用中發揮了重要作用。(來源:新浪)
