Abstract
At 9:43 AM on June 23, the 55th navigation satellite of the Beidou system, which is also the last global networking satellite of Beidou III, was successfully launched, marking the complete deployment of the Beidou III global constellation and the successful conclusion of the “three-step” strategic mission of the Beidou satellite navigation system.
As the designated unit for the “2014 Beidou Satellite Navigation Industry Major Application Demonstration Project” by the National Development and Reform Commission, China Communications Group holds two civil service qualification certificates issued by the China Satellite Navigation Positioning Application Management Center: “Beidou Navigation Civil Sub-level Service Qualification” and “Beidou Navigation Civil Terminal Service Qualification.” It is also one of the founding units and vice-chairman units of the Central Enterprise Beidou Industry Collaborative Development Platform established under the guidance of the State-owned Assets Supervision and Administration Commission this year.
China Communications Group has been actively integrating new technologies such as big data, BIM, 5G applications, and smart technologies to promote the industrial application of Beidou empowerment projects. It advances applications in areas such as full lifecycle management and monitoring and early warning based on “Beidou +,” green and intelligent transportation vehicles, intelligent services for industries, and safety and emergency response. Demonstrations of “Beidou +” applications have been carried out in full lifecycle monitoring of the new land-sea corridor, multimodal transport logistics management, automated ports, and facility safety monitoring and early warning, achieving large-scale applications in the transportation construction industry for the first time. For instance, integrated indoor and outdoor positioning technology has been promoted in several projects such as the Beijing-Shenyang High-Speed Railway, Harbin Metro, Changsha Metro, and Shanghai Metro Line 15, with Beidou + WIFI accuracy reaching meter-level; Beidou + UWB accuracy reaching centimeter-level. Beidou digital construction technology has been applied at different stages of construction, including pile foundation construction, intelligent compaction of road surfaces, and intelligent control of bulldozers. By integrating functions such as 4G/5G voice calls and remote video monitoring, the advantages of Beidou intelligent safety helmet positioning and video communication technology have been leveraged to assist the company in supervising remote projects, ensuring that remote projects, especially during the pandemic prevention and control period, maintain safe and stable production. The Beidou security products independently developed by China Communications Group, “Anyixing” (APP) and “Antubao” (handheld terminal), provide technical support for emergency command in overseas projects. In recent years, China Communications Group has collaborated with domestic universities, with projects such as “China High-Precision Positioning Network and Its Major Applications in the Transportation Field” and “Key Technologies for Integrated Positioning, Navigation, and Communication in Distant Sea Areas” winning the first prize of the National Science and Technology Award and the second prize of the National Technology Invention Award, respectively.
In 1994, the construction of the Beidou satellite navigation system was initiated. After more than 20 years, China has embarked on a path of self-reliance, independent innovation, and self-transcendence, establishing the largest, most widely covered, highest service performance, and most closely related to people’s lives complex aerospace system to date. Currently, more than half of the countries in the world have begun to use the Beidou system. In the future, China Beidou will continue to participate in international satellite navigation affairs, promote multi-system compatibility and sharing, carry out international exchanges and cooperation, and promote Beidou’s overseas applications based on the needs of the global population, sharing the latest development achievements of Beidou.
