Beidou Global Constellation Networking _ Beidou Global Constellation Deployment Completed

100s Review the significance of Beidou's global networking success.

China Beidou Global Group ended successfully today. The success of Beidou Global Group is of great significance to us, and it also proves the progress of China satellite. Therefore, it takes 100 seconds to review the history of Beidou global networking and the significance of the success of Beidou satellite networking.

100 seconds to review the history of Beidou global networking and replay the legendary road of China Beidou. 1994, Beidou-1 system project was established. The Beidou-1 system was completed in 2003, and China became the third country with its own satellite navigation system after the United States and Russia. The Beidou-2 satellite project was established in 2004. In 20 12, the world's first regional satellite navigation system with mixed constellations was successfully built. Beidou satellite navigation system officially provides regional services, and Beidou system has become one of the four international satellite navigation system service providers.

June 5438+February 2009, Beidou-3 was established. On 20 18 12.27, the Beidou-3 basic system officially provided basic navigation services to the Belt and Road Initiative and the whole world. China Beidou has taken a substantial step towards the goal of global networking. At the end of February 20 19, 19, the deployment of the core constellation of the global system was completed, which was a milestone in the successful completion of the global networking of Beidou navigation system. On June 23, 2022, the 55th Beidou navigation satellite was successfully launched, and the deployment of Beidou-3 global satellite navigation system constellation was fully completed. It is planned to build and improve a more ubiquitous, integrated and intelligent national integrated positioning navigation time service system with Beidou system as the core in 2035.

The significance of the success of Beidou satellite networking Among the four major navigation systems in the world, China Beidou system started late, but surpassed Russia and Europe, and is the most advanced and complete navigation system tied with gps at present. Wang Bo, deputy secretary-general of China Satellite Navigation and Positioning Association, believes that the Beidou-3 system was completed in a short time, which is a world space feat. In the future, it can not only provide positioning, navigation and timing services for all corners of the world, but also locate and navigate spacecraft in the adjacent space. At present, there are some frictions between China and the United States in the high-tech field. Wang Bo believes that all the core equipment of Beidou satellite is made in China and will not be affected by the "stuck neck". In addition, Beidou and gps signed a signal compatibility and interoperability agreement to provide better services to users around the world through cooperation.
