30 years of Beidou and 20 years of lunar exploration! There is a stable and healthy "Chinese coordinate" in space →
Aerospace engineering is a typical representative in the field of new productivity. While exploring the vast universe, it is also promoting the development of new materials, new energy and artificial intelligence technology.
This year, our Beidou navigation system has just celebrated its 30th anniversary, and the lunar exploration project has also entered its 20th year.
These major aerospace projects have made breakthrough progress.
This year marks the 30th anniversary of Beidou.
After 30 years of scientific research, several generations of Chinese astronauts have finally completed the "three-step" strategy, successfully launched 55 Beidou navigation satellites, and established an independent, open and compatible global satellite navigation system. One of the big suppliers.
"Build it in the sky and use it well on the ground" is the goal of the Beidou system.
Nowadays, there is a stable and healthy "Chinese coordinate" in space, and the Beidou system, like water and electricity, is everywhere and within reach.
Moreover, the Beidou system has served users in more than 200 countries and regions.
The Beidou "in the sky" has become the Beidou "around you" and the Beidou "in the world".
However, in fact, Beidou-3 faced the huge challenge of being unable to deploy stations globally at the beginning of its design.
In other words, when the satellite orbits outside the scope of my country's monitoring area, real-time measurement and control will not be possible. As a result, the accuracy of satellite navigation services will be greatly reduced.
In order to solve this problem, Lin Baojun, chief designer of the Beidou-3 satellite system, after ten years of hard work, pioneered the world's first phased array inter-satellite link technology and built a space bridge for the Beidou system, which is equivalent to building a satellite with 30 satellites. Group, one star is connected, all the stars are connected.
How accurate the navigation accuracy is depends on the onboard atomic clock, which is the "heart" of the satellite navigation system and directly determines the positioning accuracy of the satellite navigation system.
The passive spaceborne hydrogen atomic clock developed by the Shanghai Observatory of the Chinese Academy of Sciences is one of the three key technologies of the new generation of Beidou navigation satellites. It only has an error of one second in 10 million years.
The aerospace information industry is both a strategic emerging industry and a future industry.
As a giant and complex space system, Beidou-3 affects areas beyond imagination and will create infinite possibilities.
