The drone rope slowly lowered and the sampling bucket sank into the water... On the 18th, at the theme event of the 9th China (Chengdu) Smart Industry International Expo -2024 China International Beidou Large scale Application Exhibition, He Jin, the person in charge of Sichuan Wolojia Technology Co., Ltd., demonstrated a water quality automatic sampling drone. "The drone only takes a few minutes to collect water samples, and the whole process is safe, accurate, and efficient." This drone achieves precise sampling thanks to the use of the Beidou system. On the remote control in He Jin's hand, there are data information such as altitude, barometric altitude, radar altitude, and horizontal velocity listed. "The Beidou system provides precise positioning for drone sampling," He Jin said. The company has specifically developed the Beidou module, which allows drones to fly to designated locations and work efficiently even in harsh weather environments. On July 18th, the theme event of the 9th China (Chengdu) Smart Industry International Expo -2024 China International Beidou Large scale Application Exhibition opened in Chengdu.

From the precise positioning of unmanned aerial vehicles by Anyuan cameras to the early warning and forecasting of natural disasters, from the countdown of traffic lights on mobile navigation to the extremely small seeding errors of agricultural machinery, the application of Beidou has become increasingly widespread. The "2024 White Paper on the Development of China's Satellite Navigation and Location Services Industry" shows that in 2023, the overall output value of China's satellite navigation and location services industry will reach 536.2 billion yuan, an increase of 7.09% compared to 2022. The high-precision market of Beidou continues to develop, and the annual total shipment of high-precision chips and modules in China has steadily increased. The trend of widespread and large-scale high-precision applications is becoming more apparent On the same day, Liu Dake, Vice President and Secretary General of the China Satellite Navigation and Positioning Association, delivered a keynote speech at the conference, stating that the market sales, including agricultural machinery autonomous driving, high-precision vehicle navigation systems and high-precision vehicle maps, power line inspection, unmanned aerial vehicle measurement and other major scenarios, have significantly increased. With the continuous expansion of the application fields of the Beidou system, emerging markets including meteorological sounding, ocean ranching, intelligent poles, etc. have begun to rise in recent years. Liu Dake stated that by utilizing the high-precision positioning function of Beidou satellite navigation, the Beidou sounding system has improved the measurement accuracy of existing high-altitude winds by an order of magnitude; Relying on ocean surveying, Beidou navigation positioning and other technological means, the construction and management, breeding efficiency, disaster prevention and avoidance of marine pastures have been supported by basic data; Empowered by Beidou, intelligent poles have become the "nerve endings" of smart cities as a new type of information infrastructure. At present, the industry is seizing the opportunity of large-scale application of Beidou. At this exhibition, Shanghai Sinan Satellite Navigation Technology Co., Ltd. (referred to as Sinan Navigation) launched its self-developed fourth generation high-precision chip that integrates RF, power supply, baseband, and CPU. Compared to previous generations of chips, this chip is only the size of a fingernail and has lower power consumption, achieving significant improvements in performance and technology. "This chip has super computing power and can be deeply applied in fields such as the Internet of Things, digital construction, intelligent driving, measurement and mapping, precision agriculture, deformation monitoring, driving test and training, ground reinforcement, drones," said Liu Bailin, the project leader of Sinan Navigation. On July 18th, the theme event of the 9th China (Chengdu) Smart Industry International Expo -2024 China International Beidou Large scale Application Exhibition opened in Chengdu. The picture shows the fourth generation high-precision chip launched by Sinan Navigation. In the view of Pan Weifeng, Director and Senior Engineer of the Beidou Application and Ocean Business Unit of Guangzhou Southern Surveying and Mapping Technology Co., Ltd., Anyuan Photography believes that currently, Beidou empowers various industries such as water conservancy, transportation and navigation, disaster prevention and reduction, electricity, communication, surveying and mapping geographic information, petrochemicals, and mining. In the future wave of digital economy, Beidou will promote the formation of digital and intelligent application scenarios, with great potential in fields such as smart agriculture, autonomous driving, smart ports, home smart elderly care, and unmanned delivery. When it comes to the development prospects of Beidou, Liu Da said that the digital transformation and intelligent upgrading of various industries have further released the demand for satellite navigation equipment and spatiotemporal data, injecting new vitality into the development of Beidou spatiotemporal information application and service market. "The integration of Beidou industry into the digital economy has become an inevitable trend, and the spatiotemporal data generated by Beidou will create a unified spatiotemporal digital base for thousands of industries
