北斗系统赋能“北京时间”

Core Viewpoint - The Beidou system is a self-constructed global satellite navigation system in China, which not only provides positioning and navigation but also plays a crucial role in time synchronization across various industries [1][2]. Group 1: Beidou System Overview - The Beidou system is one of four global satellite timing systems, alongside the US GPS, Russia's GLONASS, and the EU's Galileo systems [1]. - The timing accuracy of the Beidou system can reach the level of 10 nanoseconds, facilitated by onboard atomic clocks [1]. Group 2: Applications and Importance - The Beidou system distributes standard time to various sectors including communication, electricity, transportation, surveying, aerospace, and national defense [1]. - Users can synchronize their local time with the standard time by receiving Beidou's broadcast signals, ensuring precise timekeeping [1].
