参“北斗”！

北斗三号全球卫星导航系统建成暨开通仪式31日上午在北京举行。中共中央总书记、国家主席、中央军委主席习近平出席仪式，宣布北斗三号全球卫星导航系统正式开通。

Chinese President Xi Jinping, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission (CMC), announced on Friday the commissioning of the BeiDou-3 Navigation Satellite System (BDS) at a ceremony marking the completion and launching of the system.

Xi and other Chinese leaders attended the ceremony at the Great Hall of the People in Beijing.

北斗“稳准狠”  

6月23日，我国在西昌卫星发射中心用长征三号乙运载火箭，成功发射北斗系统第五十五颗导航卫星，暨北斗三号最后一颗全球组网卫星。至此，30颗北斗三号全球组网卫星全部到位，我国北斗三号全球卫星导航系统星座部署全面完成。

A new and updated BeiDou-3 satellite was launched from the Xichang Satellite Launch Center in southwest China's Sichuan Province on June 23.

The satellite, carried by a Long March-3B carrier rocket, is the 30th BDS-3 satellite and the 55th in the BeiDou satellite family.

据北斗卫星导航系统工程总设计师杨长风介绍，“北斗”可以提供精密单点定位、导航、授时和短报文通信等多样化服务，广泛应用于交通运输、农林渔业、减灾救灾等诸多领域。

短报文通信是北斗的“独家秘笈”。

如果在海上没有手机信号，或是灾害发生时通信受阻，就可以通过北斗终端发送短报文。

中国及周边地区短报文通信服务，单次可发1000个汉字。全球短报文通信服务，单次可发40个汉字。

我国已有7万多只渔船和执法船安装了北斗终端，渔船遇险可通过短报文求救，目前已累计救助1万多人。

The chief designer of BDS, Yang Changfeng, said BeiDou offers its users all kinds of services. This includes accurate positioning, navigation and timing, as well as short messaging communication. The services are used in various fields, including transportation, agriculture, fishing, and disaster relief.

北斗“三步走” 

“夜望北斗知北南”，北斗七星常被当作指示方向和认识星座的重要标志，而北斗卫星导航系统的名称也正源于此。

从1994年北斗一号工程立项至今，“北斗”历经了“三步走”的发展阶段。

第一步

2000年，北斗一号系统宣布建成并投入使用。

第二步

2012年，北斗二号系统正式向亚太地区提供服务。

第三步

2020年，北斗三号全球卫星导航系统建成开通，形成35颗卫星的卫星网，信号覆盖全球。

风雨兼程二十六载，“北斗”实现了一系列目标，与美国全球定位系统（GPS）、俄罗斯“格洛纳斯”、欧洲“伽利略”构成全球四大卫星导航系统。

Named after the Chinese word for the Big Dipper or Plough constellation, China's BeiDou navigation project was launched in the early 1990s. The system then became operational within China in 2000 and in the Asia-Pacific region in 2012.

With the upgrade of its third-generation satellites, the constellation consisting of 35 satellites is ready to provide global coverage, offering an alternative to Russia's GLONASS and the European Galileo systems, as well as U.S. GPS.

仰望星空，北斗闪耀。未来，“北斗”的发展还有无限可能和广阔前景。

中国卫星导航系统管理办公室主任冉承其称，下一步，计划在2035年前建设完善更加泛在、更加智能、更加融合的国家综合定位导航授时体系，可用于从深空到深海、从室外环境到室内环境的多个区域。

Ran Chenqi, Director General of China's Satellite Navigation Office said, "The plan is to build a more general, smarter, more integrated state-level positioning, navigation and timing system by 2035, which can be used from deep space to the bottom of the ocean, from outdoor environments to indoor environments."

中国北斗的传奇，未完待续。
