中國北斗導航系統開啟全球服務

China’s BeiDou Navigation Satellite System (BDS) has started to provide global service, said BDS Spokesperson Ran Chengqi on Thursday.

北斗衛(wèi)星導航系統新聞發(fā)言人冉承其周四宣布：北斗衛(wèi)星導航系統建設基本完成，已經開始提供全球服務。

At a press conference of the State Council Information Office, Ran said the construction of the BDS-3 primary system had been completed.

在國務院新聞辦公室舉行的新聞發(fā)布會上，冉承其表示，北斗三號系統的建設已經完成。

This signifies that BDS has officially entered the global era as the BDS expands from a regional system to a global navigation system, Ran said.

他說:“這標志著北斗系統正式進入全球時代，北斗系統從區(qū)域導航系統擴展到全球導航系統。”

From now on, no matter where you go, BDS will always be with you, said Ran.

冉承其說:“從現在開始，無論你走到哪里，北斗系統都會一直跟隨著你。”

The positioning accuracy of the system has reached 10 meters globally and five meters in the Asia-Pacific region. Its velocity accuracy is 0.2 meters per second, while its timing accuracy stands at 20 nanoseconds, according to Ran.

該系統全球定位精度10米，亞太地區(qū)定位精度5米。根據冉承其提供的數據，它的速度精度為0.2米每秒，而計時精度為20納秒。

By the end of 2018, there were a total of 33 BDS satellites operating in orbit, including 15 BDS-2 satellites and 18 BDS-3 satellites.

截至2018年底，在軌運行的北斗系統衛(wèi)星33顆，其中北斗2號衛(wèi)星15顆，北斗3號衛(wèi)星18顆。

China plans to launch another 11 BDS-3 satellites and one BDS-2 satellite in the coming two years to form the complete global network, which will further enhance the global service performance, Ran said.

中國計劃在未來兩年內再發(fā)射11顆北斗3號衛(wèi)星和1顆北斗2號衛(wèi)星，形成更加完整的全球網絡，進一步提升全球服務水平。
