2020年6月23日，北斗系统的最后一颗组网卫星发射升空。这标志着北斗导航系统全球星座部署正式完成。 Yesterday, China’s last satellite of its BeiDou Navigation Satellite System (BDS) was launched into orbit, marking the completion of the whole system.
2020年6月23日，北斗系统的最后一颗组网卫星发射升空 在中国，古人利用北斗七星——大熊星座最亮的七颗星——测定方位。中国卫星导航系统以“北斗”为名，暗含了“指明方向”的寓意。 In ancient China, people used the Big Dipper, which is known in Chinese as "beidou qixing," to navigate. China’s navigation satellite system is named after "Beidou", which carries the meaning of "pointing out the right direction." 1994年，中国正式启动了北斗卫星导航实验系统建设。经过26年，3次技术迭代，现在的北斗导航系统已经拥有55颗导航卫星，能够面向全球提供服务。 China started constructing the BeiDou Navigation Satellite Experimental System (BDS-1) back in 1994. The system has undergone multiple technical iterations over the past 26 years, and now it comprises 55 satellites and can provide services worldwide.
北斗导航卫星星历星座图 相比于其他卫星导航系统，更多高轨卫星、多频信号组合，给予了北斗更高的抗遮挡能力，能够让其提供更高精度的服务，目前，其水平和高程定位精度实测均优于5米。 Compared with other satellite navigation systems, the BDS operates more satellites in high orbit, and transmits navigation signals at more frequencies. These features enable better anti-shielding capabilities and more accurate services. Currently, both the system's horizontal positioning and height measurement accuracy is within five meters. 除了导航，北斗系统还能够提供较为多元的特色服务，例如，短报文通信和免费国际搜救服务。 Apart from navigation, the BDS also provides diverse services, such as short message communication, and free international search and rescue assistance.
2019年，森林消防员使用背负式北斗系统的短报文功能传输火场坐标及基本情况 在恶劣环境中，求救者可以通过短报文功能，经由北斗卫星发出定位和救援信息，而北斗的返向链路可以向求救者发送信息回执，让求救者了解施救进度，大大增强其被救信心。 In a harsh environment, people in distress can send short messages to transmit their location and an SOS signal via the Beidou satellites. A reply will then be sent through a reverse link, updating the help-seekers on the rescue progress, thus give them more confidence of being rescued. 北斗系统已经应用在了中国的交通、农业等传统领域。经由北斗纳入营运车辆动态监管系统的车辆已经超过650万辆；北斗也在不断与工业互联网、车联网等新领域融合，创新出了自动物流、自动泊车等应用。随着5G商用普及，北斗和新技术加速融合，新的应用模式也在不断涌现。 The BDS has been applied in transportation, agriculture and other traditional fields. More than 6.5 million commercial vehicles have been included in a monitoring system based on the BDS. The navigation system is also integrated with the industrial internet, the Internet of Vehicles and has been applied in other new fields. Various innovative applications have been launched, such as automatic logistics and parking. As the commercial use of 5G expands, the integration of the BDS with new technologies is accelerating, and new application models continue to emerge.

BDS-related products are now being used in more than 120 countries and regions. Projects based on the BDS for precision farming, smart port construction and digital construction have been carried out in many countries across Asia, Europe and Africa. China is also actively communicating with Russia, the United States and European countries to improve the compatibility of the BDS so that it can better serve its global users.
