Xinhua News Agency, Shanghai, September 4th (Reporter Zhang Jiansong) The vigorous development of satellite navigation applications has always been accompanied by innovations and breakthroughs in aerospace technology. Beidou satellite navigation system is one of the world's four major satellite navigation core suppliers, and currently has 39 satellites in orbit.
According to Yang Jun, deputy director of the China Satellite Navigation System Management Office, at the 8th International Conference on Space Technology Innovation held in Shanghai on the 4th, the construction of the Beidou-3 system has entered an ultra-high-density launch since the end of 2017. At present, Beidou System officially provides RNSS services to the world, with a total of 39 satellites in orbit. This year, another 5-7 satellites will be launched. After launching another 2-4 satellites next year, Beidou global system construction will be fully completed.
He said that the Beidou system always takes innovation and development as the driving force. Through innovation to promote technological development, the space-borne atomic clock has been improved by three orders of magnitude, and satellite positioning accuracy has been steadily improved; by expanding the function, on the basis of further improving the global navigation positioning timing performance and regional short message communication service capabilities, the global short report Service capabilities such as communications, international search and rescue, satellite-based enhancement, and precise single-point positioning contribute "Chinese wisdom" to world aerospace technology.
Innovation also promotes the development of the application industry. The inexpensive Beidou chip is entering the 28nm era. By establishing a ground-based reinforcement system, it has achieved a nationwide network to provide high-quality and high-precision services. By carrying out industry and regional demonstrations, it has promoted the healthy development of the Beidou industry ecology.
Yang Jun said that the Beidou system always adheres to open cooperation and resource sharing. Compatible and interoperable with GPS and Gronas. Beidou Navigation System also joined international organizations such as international civil aviation, international maritime affairs, and 3GPP mobile to accelerate integration into global services and contribute "China power" to world satellite navigation.
The 8th International Conference on Aerospace Technology Innovation (Shanghai, China), co-sponsored by the International Academy of Astronautics, the Chinese Academy of Astronautics, and the Shanghai Institute of Aerospace Technology, focuses on "Breakthrough Space Technology Innovation". During the two-day conference, more than 300 experts and scholars from 14 countries and regions, including the United Kingdom, the United States, Russia, Japan, and Israel, discussed topics related to rockets, satellites, space stations, robot space exploration, and commercial space. Carry out in-depth discussions to further expand international cooperation in the aerospace field.
