Beidou Global System Constellation Launch Reality _ Beidou Global System Constellation Deployment

The most unforgettable moment, remember the successful launch of Beidou-3?

Perfect ending, the stars shine in the world! A few days ago, China successfully launched the 55th Beidou navigation satellite, the last global networking satellite Beidou-3, in xichang satellite launch center with the Long March 3B. Up to now, the deployment plan of Beidou-3 global satellite navigation system constellation has been completed six months ahead of schedule.

The final launch mission of Beidou-3 has experienced many obstacles. Previously, due to the failure of two consecutive launch missions, the whole project plan was postponed and the quality review was conducted again. The launch time was therefore adjusted from May to June. Just a few days before the launch, the plan was postponed again to ensure that there would be no hidden dangers due to the technical problems found. The successful launch of this mission fully embodies the lofty scientific spirit and rigorous work style of China astronauts. This proves once again that the policy of 16 has made great contributions to overcoming difficulties and winning victories in China's space industry.

After Beidou-3 successfully completed its final mission, the United Nations Office for Outer Space Affairs sent a special video to congratulate Beidou on completing all the established tasks. They believe that Beidou is promoting global economic and social development, and appreciate Beidou's great contribution to the peaceful use of outer space and the efforts made by Beidou system in United Nations space activities.

At present, all Beidou-3 satellites have entered the long tube mode. Xi 'an Satellite TT&C Center is actively carrying out the on-orbit test of platform and inter-satellite link, and strives to provide navigation services for early access to inter-satellite link system and network access.

When the satellite is transferred to the remote management stage, high-level operation and maintenance management is very important. It is reported that Xi 'an Satellite TT&C Center has many years of experience in Beidou navigation satellite management. They are constantly improving their knowledge of satellite diagnosis and making plans for satellite fault handling in advance. At the same time, according to the characteristics of the satellite, the automatic control software is developed. Fill the remote control instruction and telemetry standard into the specific program, and the program generates the instruction block with one key. This saves a lot of time and energy for researchers and makes satellite management more scientific and efficient.

China's Beidou system serves the world and benefits mankind. Where mankind advances, there must be the guidance of Beidou navigation system. In the future, China will build a more extensive, comprehensive and intelligent integrated space-time system, further enhance its capabilities and make contributions to the further development of mankind.
