中国北斗导航系统开启全球服务

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

北斗卫星导航系统新闻发言人冉承其周四宣布：北斗卫星导航系统建设基本完成，已经开始提供全球服务。

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

在国务院新闻办公室举行的新闻发布会上，冉承其表示，北斗三号系统的建设已经完成。

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.

他说:“这标志着北斗系统正式进入全球时代，北斗系统从区域导航系统扩展到全球导航系统。”

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

冉承其说:“从现在开始，无论你走到哪里，北斗系统都会一直跟随着你。”

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.

该系统全球定位精度10米，亚太地区定位精度5米。根据冉承其提供的数据，它的速度精度为0.2米每秒，而计时精度为20纳秒。

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，在轨运行的北斗系统卫星33颗，其中北斗2号卫星15颗，北斗3号卫星18颗。

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.

中国计划在未来两年内再发射11颗北斗3号卫星和1颗北斗2号卫星，形成更加完整的全球网络，进一步提升全球服务水平。
