The deployment of Beidou-3 global satellite navigation system constellation was completed six months ahead of schedule?

The constellation deployment of Beidou-3 global satellite navigation system was successfully completed on June 23rd, half a year ahead of schedule. The success of Beidou-3 will contribute a lot to the future, which is of great significance. So let's introduce the constellation knowledge in detail!

The deployment of Beidou-3 global navigation system constellation was completed half a year ahead of schedule. 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 by long march 3b in xichang satellite launch center. So far, the deployment of Beidou-3 global navigation satellite constellation was fully completed half a year ahead of schedule.

The final launch of Beidou-3 was full of twists and turns. Previously, due to the failure of two space launch missions, the whole project was extrapolated to conduct quality review, and the launch time was adjusted from May to June; On June 16th, the launch was postponed again due to technical problems found before the launch, in order to ensure 1% success without any hidden dangers. The complete success of this mission fully embodies the scientific spirit of seeking truth from facts and the strict and meticulous work style on the space front, and once again proves that the 16-character policy of "being serious, thoughtful, meticulous, reliable and foolproof" is an important magic weapon for China's space industry to constantly overcome difficulties and win victories.

After the successful launch, the United Nations Office for Outer Space Affairs sent a special video to congratulate Beidou system on its global networking deployment, affirming that Beidou system is promoting global economic and social development, and appreciating its great contribution to the peaceful use of outer space and participation in international cooperation in United Nations space activities. The satellite launched this time belongs to the geostationary orbit satellite. After a series of on-orbit tests, China will conduct the Beidou system-wide joint debugging test. On the basis of ensuring the stable and reliable operation of the system and excellent performance indicators, we will provide users with all-day, all-weather, high-precision global positioning and navigation time service, as well as satellite-based enhancement, short message communication, precise single point positioning and other special services.

in p>1994, Beidou satellite navigation system started construction. Over the past 2 years, China has organized 44 Beidou launch missions in xichang satellite launch center * * *. Four Beidou-1 test satellites, 55 Beidou-2 and Beidou-3 networking satellites have been put into the scheduled orbit by using the Long March 3A series of launch vehicles, and the mission success rate is 1%. Especially since the global networking was launched in 217, 18 launch missions have been carried out at high density in two and a half years. This year, in the special environment of fighting against * *, the Beidou project adhered to the "two-line operation" of networking launch prevention and control, which effectively promoted the successful conclusion of the Beidou-3 global networking. With the strong support of measurement and control, ground transportation control, inter-satellite link transportation management, application verification and other systems, all the satellites in orbit launched before have been connected to the network.

significance from project demonstration to implementation, from dual-star positioning to regional networking, and then to global coverage, China's satellite navigation system construction has gone through more than 3 years of exploration and practice, and three generations of Beidou people have continued to struggle, and has embarked on a road of self-reliance, independent innovation and self-transcendence. It has built a huge and complex space system with the largest scale, the widest coverage, the highest service performance and the closest connection with people's lives in China, becoming the first one in China to provide public services to the world.
