China Satellite Internet Constellation Time

The deployment of Beidou-3 global satellite navigation system constellation was fully completed, and Musk sent a "congratulatory message": congratulations to Beidou.

At 9: 43 on June 23rd, China successfully launched the 55th navigation satellite of Beidou system and the last global networking satellite of Beidou-3 in xichang satellite launch center by Long March 3B. At this point, the deployment of Beidou-3 global satellite navigation system constellation was fully completed six months ahead of schedule.

After the successful launch, Zhou Hengxing, the founder of pandaily, an English-language media that introduced China's science and technology industry overseas, sent an email to Musk, the founder of Space Exploration Technology Company, saying that the last satellite of Beidou-3 had been launched into orbit. On the evening of June 24th, Musk "congratulated Beidou" in the email reply.

In 1980s, China began to explore the development path of satellite navigation system suitable for China's national conditions, and formed a "three-step" development strategy. Since 1994 started the construction of Beidou-1 project, the construction of satellite navigation system in China has achieved rapid leap in the past 26 years. China has launched 59 Beidou satellites, including 55 Beidou navigation satellites, 4 Beidou navigation test satellites, and the late localization of Beidou-3 100%.

In 2000, China built the Beidou-1 system to provide services for users in China. At the end of 20 12, Beidou-2 system was built in China to provide services for users in the Asia-Pacific region. 20 17, 1 1, China Beidou-3 successfully launched the first group of binary stars, and the Beidou system entered the era of globalization.

Now the global constellation of Beidou-3 system has been deployed, and Beidou-3 system is about to complete the global networking. "The completion of the Beidou system is not only a symbol of a space power, but also the first time that China has provided public services to the world. The key is that we are still free. " Ran Chengqi, director of China Satellite Navigation System Management Office, said.

Just as "satellite navigation is only limited by people's imagination", Yang Changfeng, chief designer of Beidou satellite navigation system engineering, said, "I believe Beidou system will bring more surprises to the world."
