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

The deployment of Beidou-3 global satellite navigation system constellation was successfully completed on June 23rd, half a year ahead of schedule. The success of Beidou-3 has made great contributions to the future and is of great significance. Then let's introduce the constellation knowledge in detail for everyone!

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. So far, the deployment of Beidou-3 global satellite navigation system constellation was fully completed six months ahead of schedule.

Beidou-3 closed in a zigzag way. Previously, due to the failure of two space launch missions, the whole project was extrapolated for quality review, and the launch time was adjusted from May to June; On June 16, due to technical problems found before the launch, the launch was postponed again to ensure that100 was successful without any hidden dangers. The complete success of this mission fully embodies the scientific spirit of seeking truth from facts and the rigorous and meticulous work style of the space front, and once again proves that the 16-character policy of "earnest, thoughtful, meticulous, reliable and foolproof" is an important magic weapon for China's space industry to constantly overcome difficulties and win victory.

After the successful launch, the United Nations Office for Outer Space Affairs sent a special video to congratulate the global networking deployment of Beidou system, affirm that Beidou system promotes global economic and social development, and appreciate Beidou system's 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, it provides users with all-weather, all-weather and high-precision global positioning and navigation timing services, as well as satellite-based enhancement, short message communication, accurate single point positioning and other special services.

1994, Beidou satellite navigation system started construction. In the past 20 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 predetermined orbit by using the Long March 3A series launch vehicles, and the mission success rate is 100%. Especially since the global networking began on 20 17, 18 launch missions have been carried out with 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 global networking of Beidou-3. With the strong support of measurement and control, ground transportation control, inter-satellite link transportation management, application verification and other systems, all the previously launched satellites in orbit have been networked.

Significance From project demonstration to implementation, from two-star positioning to regional networking, and then to global coverage, China's satellite navigation system construction has gone through more than 30 years of exploration and practice. Three generations of Beidou people have continued to struggle and embarked on a road of self-reliance, independent innovation and self-transcendence. It has built a huge 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 in China to provide public services to the world.
