近日,我国首个配有地基增强系统的基站在新疆维吾尔自治区首府乌鲁木齐市建成,将为电力行业提供高精度的定位、授时和应急通信服务。该基站的增强系统由国产的北斗卫星导航系统提供,该系统可将动态定位精度提升至厘米级,静态定位精度提升至毫米级。
The first base station with a ground-based augmentation system is completed in Urumqi, capital of Xinjiang Uygur autonomous region, which will offer high-precision positioning timing and emergency communication for the electricity industry. Provided by the China-made Beidou Navigation Satellite System, the station's augmentation system can increase positioning precision to centimeter-level dynamically and millimeter-level statically.
6月23日,我国北斗三号全球卫星导航系统最后一颗组网卫星在西昌卫星发射中心点火升空。 中国高度重视北斗系统建设发展,自 20 世纪 80 年代开始探索适合国情的卫星导航系统发展道路,形成了“三步走”发展战略:2000 年年底,建成北斗一号系统,向中国提供服务;2017 年年底,建成北斗二号系统,向亚太地区提供服务;计划 2020 年前后,建成北斗三号系统,向全球提供服务。2035 年前,将以北斗系统为核心,建设完善更加泛在、更加融合、更加智能的国家综合定位导航授时体系。
目前,全世界一半以上的国家都开始使用北斗系统。后续,中国北斗将持续参与国际卫星导航事务,推进多系统兼容共用,开展国际交流合作,根据世界民众需求推动北斗海外应用,共享北斗最新发展成果。
