历经10年，青海北斗卫星导航系统从建设、应用到科普，迈出三大步——从“天边”到“身边”

Core Viewpoint - The development of the BeiDou satellite navigation system in Qinghai has made significant progress over the past decade, advancing in three main areas: network construction, application, and popularization [3][16]. Group 1: BeiDou Network Construction - In 2015, the Qinghai Provincial Institute of Basic Surveying and Mapping established a research team to address the urgent need for spatial benchmarks in various sectors, leading to the construction of a BeiDou navigation system [5][6]. - By July 2021, the team completed the establishment of 116 BeiDou satellite navigation positioning reference stations across economically developed areas and major counties in Qinghai, laying the foundation for future applications [6][7]. - The modern surveying benchmark service system in Qinghai has been built around a core of "BeiDou reference station network + digital elevation benchmark model + high-grade gravity network," achieving multiple technological milestones and awards [6][7][8]. Group 2: BeiDou Applications - The BeiDou high-precision benchmark service platform has provided over 2 million spatial benchmark services to 312 enterprises and institutions, replacing traditional control networks and enhancing efficiency [7][10]. - In various applications, such as road construction in Guoluo Prefecture, the integration of BeiDou technology with drones has improved surveying efficiency by over 60% and reduced labor costs by 50% [10][11]. - The BeiDou system has also enhanced meteorological monitoring capabilities in Haidong City, allowing for rapid updates and accurate tracking of weather conditions, thus improving disaster prevention and water resource management [11][12]. Group 3: BeiDou Popularization - The establishment of the Qinghai BeiDou Scientific Popularization Base has facilitated over 80 educational activities, reaching more than 10,000 students and promoting awareness of the BeiDou system [14][19]. - The base aims to cultivate innovation and scientific spirit among students, particularly in remote and ethnic areas, by providing hands-on experiences with BeiDou technology [14][15]. - In 2024, Qinghai's BeiDou team participated in the "15th BeiDou Cup" national youth aerospace technology competition, achieving notable success with multiple awards [14][15].
