　　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.
