The recent short recording clip of 1 10 second made people cry. This is the glorious years of Beidou for 20 years, and it is also the road to growth in these 20 years. ? Beidou? A household name, a proud name and a passionate name. He opened a new chapter in the history of our country, which is the greatest masterpiece completed by our country in the past 20 years.

The first Beidou navigation test satellite was launched in 2000, the first Beidou navigation satellite was successfully launched in 2007, and Beidou II was launched in 20 12. One arrow and two stars? Successfully launched, the Beidou-3 satellite system was launched in 20 17, and the Beidou-3 global satellite navigation system constellation was successfully deployed in 2020. Beidou has experienced 20 years of growth, from one? Children? Has grown into a giant who can hold his head high.

Looking back on these 20 years, it is a 20-year retrospective of our whole nation, and it is also a 20-year suffering. For 20 years, we have been restricted and laughed at by others because we don't have our own satellite navigation system. This has had a very negative impact on the review in many fields. China's Beidou satellite navigation system was planned at that time, and it is far from mature and brilliant today, so we have to bear all this.

In the past 20 years, in order to make China's own satellite navigation system available as soon as possible, countless people in China have made great efforts, and countless scientists have invested precious youth, time and all their energy. For this goal, they paid all, and the final result certainly did not disappoint them.

Beidou grew up in their generation and will certainly grow up in our generation. As the owners of predecessors' great achievements, in addition to enjoying all this, we have a more arduous task, that is, to carry forward these achievements, so as not to let their hard work be in vain and our life miserable. With this goal, all of us are on the road, under the light of Beidou.
