01 Technology Expo, Beidou application enters a new stage

The 4th Beidou Scale Application International Summit will be held in Zhuzhou, Hunan Province from September 24th to 28th, 2025. As an international event in the field of large-scale application of Beidou, this summit, with the theme of "Together with the World, Together with Beidou Intelligent Connection Time and Space", has attracted delegations from 24 countries, more than 5000 guests, and 112 enterprises from around the world to participate. The exhibition lineup covers the entire industry chain, including satellite navigation chips, terminal equipment, and communication services.

This summit is jointly organized by the National Development and Reform Commission, the Cyberspace Administration of China, the Ministry of Industry and Information Technology, the Ministry of Transport, and the People's Government of Hunan Province. As a representative enterprise in the field of Beidou application in Zhejiang Province, Saisi was specially invited by the Zhejiang Provincial Development and Reform Commission to showcase Beidou timing technology and full stack time-frequency solutions at the E3 Hall of the Zhejiang Provincial Exhibition Group, becoming one of the key forces in the construction of the "smart connected space-time" new ecology in the Zhejiang Exhibition Group.

02 Precise debut: The full stack time-frequency solution interprets the "pulse of time and space"

This summit has set up provincial-level exhibition halls, and the Zhejiang Provincial Pavilion has the theme of "Empowering Beidou and Smart Mapping Zhejiang", showcasing the deep application of Beidou in intelligent driving, smart agriculture, low altitude economy and other fields, fully demonstrating the "international scope" and "technological sense" of Beidou application.

"From the early double star regional test of Beidou 1 to the present, the Beidou signal has covered more than 200 countries and regions around the world; the positioning accuracy has jumped from 10 meters to sub meters, and the time synchronization ability has entered the nanosecond era." Li Jiancheng, academician of the CAE Member and president of Central South University, mentioned a set of exciting comparisons in the keynote speech of the Beidou Summit.

How can Beidou continue to steadily pursue the path of independent innovation? As a domestic enterprise in the field of Beidou timing, Saisi has presented its innovative Beidou application with Saisi's characteristics through the display of high-performance clock chips, crystal oscillators, atomic clocks, timing boards, and time servers compatible with Beidou signals, as well as the "single/double Beidou" full stack time-frequency solution at this exhibition. It vividly demonstrates how high-precision time synchronization injects precise "spatiotemporal pulse" into the digitalization of thousands of industries, attracting a large number of guests, industry experts, and potential partners to stop and exchange ideas.

03 Achievement Implementation: Deeply Empowering Key Industries, Highlighting "Chinese Precision"

As a practitioner and promoter of the large-scale application of Beidou, the full stack products and solutions of Saisi Beidou timing have blossomed in key fields such as manufacturing, artificial intelligence, industrial Internet of Things, 5G/6G, autonomous driving, and smart cities, becoming the "infrastructure" of the digital economy era.

In terms of operators, Saisi Electronics has partnered with China Mobile to establish the "Beidou+5G+Time Service" integrated application project, jointly developing the Beidou common view industry standard, representing domestic Beidou time service; In terms of power, we have undertaken the construction of a power single Beidou sky earth mutual backup time-frequency integrated clock synchronization network, achieving nanosecond level accuracy, reducing network latency by over 50%, and achieving a GNSS interference and deception signal rejection rate of 99.99%. We have also achieved large-scale deployment in more than ten provinces across the country; In terms of rail transit, over 50% of the newly built subway clock systems in China have been completed, as well as the single/double Beidou synchronous transformation of multiple subway lines such as Kunming, Urumqi, Xinjiang, Jinan, Chengdu, Taiyuan, and Qinghai Tibet Railway.

04 Co creating the future: Empowering the global intelligent connected ecosystem with "Chinese precision"

"The functions of the Beidou system are the largest among similar satellites in the world." Liu Jingnan, an academician of the CAE Member and a professor of Wuhan University, said in an interview at the Beidou Summit that, facing the future, the Beidou system should empower each other with emerging technologies, promote cross innovation with other fields, and constantly promote innovative research and development of software and platforms.

The relevant person in charge of Saisi expressed sincere gratitude to the government departments for their recognition and support of Saisi. It is also an honor to represent the Zhejiang time-frequency innovation force at this year's Beidou Summit. Time synchronization is the invisible cornerstone of the Internet of Things, and Saisi's mission is to transform the "invisible" precision into visible benefits and reliability in various industries. In the future, we will continue to deepen the research and development of time-frequency technology, collaborate with industry chain partners for innovation, deepen the innovative application of Beidou, and help the construction of "smart connected space-time" move towards a new stage of higher precision, wider coverage, and deeper integration. Together with numerous industry partners, we will write a new chapter in "smart connected space-time".
