中国北斗的进化：从“天边”到“身边”（瞰前沿）

Core Insights - The Beidou satellite navigation system has entered a new phase of large-scale application, integrating into national infrastructure and various sectors including aviation and maritime, and is recognized by 11 international organizations [2][4]. Technological Advancements - The Beidou system has upgraded its onboard atomic clock configuration and introduced new inter-satellite link terminals, maintaining world-class stability, precision, and continuity since its global networking five years ago [4][5]. - The new atomic clock can achieve an accuracy of 1 second over 300 million years, significantly enhancing the timing performance of the Beidou system [5]. - The inter-satellite link technology allows for efficient communication and data transmission among satellites, improving overall system performance [5][6]. New Applications - The integration of Beidou with technologies such as big data, AI, IoT, and 5G has led to innovative applications across various industries, exemplified by the synchronization of traffic lights for improved traffic flow [6][7]. - As of the end of 2024, the total application of Beidou terminal devices in major industries is nearing 30 million units, with over 2.3 billion Beidou-compatible chips shipped [8]. Future Trends - The next-generation Beidou system is set to be completed by 2035, with plans to extend its capabilities to lunar and deep space navigation, forming a "mini system" on the moon [9][10]. - A recent achievement includes the establishment of the first international constellation in the Earth-Moon space, which will support navigation and communication services for future lunar missions [10].
