中国北斗卫星导航系统(BDS)是中国自行研制的全球卫星导航系统,也是继 GPS、GLONASS 之后的第三个成熟的卫星导航系统。北斗卫星导航系统(BDS)和GPS、GLONASS、GALILEO 是联合国卫星导航委员会已认定的供应商。

China Beidou satellite navigation system (BDS) is a global satellite navigation system developed by China and the third mature satellite navigation system after GPS and GLONASS. Beidou satellite navigation system (BDS), GPS, GLONASS and Galileo are suppliers recognized by the United Nations satellite navigation Committee.

中国北斗卫星导航系统(英文名称:BeiDou Navigation Satellite System,简称 BDS)是中国自行研制的全球卫星导航系统,也是继 GPS、GLONASS 之后的第三个成熟的卫星导航系统。北斗卫星导航系统(BDS)和美国 GPS、俄罗斯 GLONASS、欧盟 GALILEO,是联合国卫星导航委员会已认定的供应商。

Beidou navigation satellite system (BDS) is a global satellite navigation system developed by China and the third mature satellite navigation system after GPS and GLONASS. Beidou satellite navigation system (BDS) and GPS of the United States, GLONASS of Russia and Galileo of the European Union are suppliers recognized by the United Nations satellite navigation Committee.

北斗卫星导航系统由空间段、地面段和用户段三部分组成,可在全球范围内全天候、全天时为各类用户提供高精度、高可靠定位、导航、授时服务,并具短报文通信能力,已经初步具备区域导航、定位和授时能力,定位精度为分米、厘米级别,测速精度 0.2 米/秒,授时精度 10 纳秒。

Beidou satellite navigation system is composed of three parts: space segment, ground segment and user segment. It can provide high-precision and reliable positioning, navigation and timing services for all kinds of users all over the world, and has the ability of short message communication. It has initially possessed the ability of regional navigation, positioning and time service. The positioning accuracy is decimeter and centimeter level, and the speed measurement accuracy is 0.2 Time of service, 10 nm accuracy.

2020 年 7 月 31 日上午,北斗三号全球卫星导航系统正式开通。

On the morning of July 31, 2020, the beidou-3 global navigation satellite system was officially opened.

北斗卫星导航系统(以下简称北斗系统)是中国着眼于国家安全和经济社会发展需要,自主建设、独立运行的卫星导航系统,是为全球用户提供全天候、全天时、高精度的定位、导航和授时服务的国家重要空间基础设施。

Beidou satellite navigation system (hereinafter referred to as Beidou System) is a satellite navigation system independently constructed and operated by China with a view to the needs of national security and economic and social development. It is an important national space infrastructure that provides global users with all-weather, all-weather, high-precision positioning, navigation and timing services.

随着北斗系统建设和服务能力的发展,相关产品已广泛应用于交通运输、海洋渔业、水文监测、气象预报、测绘地理信息、森林防火、通信时统、电力调度、救灾减灾、应急搜救等领域,逐步渗透到人类社会生产和人们生活的方方面面,为全球经济和社会发展注入新的活力。

With the development of Beidou system construction and service capacity, the related products have been widely used in transportation, marine fisheries, hydrological monitoring, weather forecasting, surveying and mapping geographic information, forest fire prevention, communication time system, power dispatching, disaster relief and disaster reduction, emergency search and rescue, etc., and gradually penetrated into all aspects of human social production and people’s life, and injected into the global economic and social development New energy.

卫星导航系统是全球性公共资源,多系统兼容与互操作已成为发展趋势。中国始终秉持和践行“中国的北斗,世界的北斗”的发展理念,服务“一带一路”建设发展,积极推进北斗系统国际合作。与其他卫星导航系统携手,与各个国家、地区和国际组织一起,共同推动全球卫星导航事业发展,让北斗系统更好地服务全球、造福人类。

Satellite navigation system is a global public resource. Multi system compatibility and interoperability has become a development trend. China China has always adhered one’s own to one belt, one road, the other is the development of the “Beidou and the Beidou”, and actively promoted the international cooperation of the Beidou system. Together with other satellite navigation systems, together with various countries, regions and international organizations, we will jointly promote the development of global satellite navigation, so that the Beidou system can better serve the world and benefit mankind.
