Recently, Sichuan Taifu has received good news: The company, relying on its profound technical accumulation and outstanding project implementation capabilities in the fields of time synchronization and Beidou application, has successfully won the bid for the China Railway Hohhot Clock Synchronization Network Equipment Single Beidou Transformation Project, the Clock Synchronization Equipment Transformation Project of Chengdu Bureau Group Co., Ltd., and the Time Clock Equipment Project of the Newly Built Guangzhou-Zhanjiang Railway. These successful bids not only mark a major breakthrough for Sichuan Taifu in promoting the “indigenization, autonomy, and controllability” of the country’s key infrastructure time synchronization systems, but also fully demonstrate the company’s comprehensive strength and leading advantages in high-precision positioning and time-frequency technology.
Time synchronization is the “nerve center” for the stable operation of critical infrastructure such as power, communication, and finance. With the full completion and commissioning of China’s Beidou-3 global satellite navigation system, adopting the “single Beidou” mode for high-precision timing has become a strategic choice to enhance national information security and achieve independent control of the timing system, which is of great significance for reducing reliance on foreign satellite navigation systems.
With the full completion and official launch of the Beidou-3 global satellite navigation system, China’s satellite navigation and location service industry has fully entered a new development stage dominated by Beidou. The so-called “single Beidou transformation” refers to the complete switch of the original equipment that relied on foreign navigation systems such as GPS to solely rely on China’s Beidou system for positioning, navigation and timing functions. This move not only significantly enhances the security level of the country’s key infrastructure and strengthens the system’s autonomy and controllability, but also helps to fully leverage the unique advantages of the Beidou system in high-precision timing and short message communication, providing more reliable and diverse service support for various industry applications.
The above-mentioned winning projects aim to provide a set of safe, reliable and efficient domestic positioning solutions for China’s railway transportation sector. They are of great significance for ensuring the safety of urban transportation operations, enhancing the management level of the industry, and promoting the development of the Beidou industrial ecosystem. The clock synchronization network is the “nerve center” and “time heart” of the railway communication system, providing a unified, precise and reliable time reference for all core business systems such as train control, dispatching command and passenger services. The above-mentioned renovation projects aim to comprehensively upgrade the existing clock synchronization equipment that relies on foreign GPS systems to equipment that uses China’s independently developed Beidou Satellite Navigation System (BDS) as the sole time source.
Upon the completion of the project, two core values will be achieved:

1. Safety, autonomy and controllability: Completely break away from the technical reliance on foreign satellite navigation systems, effectively avoid potential risks such as signal interruption, accuracy reduction, and malicious interference, greatly enhance the safety and reliability of key railway infrastructure in China, and build a “time barrier” for the safety of national railway transportation.
2. High Precision and High Reliability: The Beidou-3 global system features internationally leading timing accuracy and stability. A single Beidou clock synchronization device will provide nanosecond-level high-precision time synchronization signals for various railway systems, ensuring the efficient, coordinated and stable operation of core services such as train operation diagrams, signal interlocking, and CTC (Centralized Traffic Control), laying a solid foundation for the future construction of intelligent railways.
   The above-mentioned winning of the bid not only represents the high recognition of Sichuan Taifu’s technical strength and service level by the client, but also marks another milestone for the company in the field of “single Beidou” transformation in key industries. In the winning project, Sichuan Taifu will continue to provide high-quality services to China State Railway Group and various railway bureaus, ensuring the reliable operation of the equipment. In the future, it will continue to track the “single Beidou” transformation projects of the synchronous network of various railway bureaus, providing more railway bureaus with high-quality services of Sichuan Taifu’s Beidou equipment. It will continue to adhere to the development concept of “independent innovation and security controllability”, and continuously deepen the research and application of time synchronization and Beidou technology, contributing to the digital transformation and security guarantee of more industries.
