One arrow and eight stars have made my motherland.

Jilin-1 satellite networking program extraction upgrade!

China's space satellites are completely independent and self-contained, and will fully serve all fields of China's socialist economic construction!

Cheer for the great motherland! ! !

On May 5, 2022 10: 38, the width of Changchun-Guangzhou satellite "Jilin No.1" was 0 1C, and eight satellites were launched by the Long March II carrier rocket at Taiyuan Satellite Launch Center. The satellite successfully entered the scheduled orbit and the launch mission was successful!

This mission is the19th launch of the "Jilin-1" satellite project. After eight launched "Jilin No.1" satellites are put into orbit, they will be networked with 46 "Jilin No.1" satellites in orbit. So far, the number of "Jilin-1" satellites in orbit has increased to 54, and it can visit any part of the world 17 20 times a day, providing more abundant remote sensing data and products and services for agriculture, forestry, ocean, resources, environmental protection, urban construction and scientific experiments.

On April 30, 2022, Jilin No.1 China launched five satellites into the East China Sea by the Long March 11 Sea-launched Remote 3 carrier rocket. The satellites successfully entered the scheduled orbit and the launch mission was a complete success! !

It is estimated that around 2025, Jilin No.1 will realize 138 satellites networking!
