What are the satellite chains for? The real version of the galaxy train.

In fact, Star Satellite is a project of American Space Exploration Technology Company, and the research began in June 20 15. It has attracted the attention of the whole world and is regarded as a realistic version of the "Galaxy Train". So what is a satellite chain and what is its use? Then let's use constellation knowledge to reveal what the next satellite chain is for!

What's the use of satellite links? If all goes well, satellite links can provide low-cost internet connection services around the world.

Joint Satellite: The United States launched a joint satellite before the real Galaxy train. Satellite transit, just like the "Galaxy train" falling from the sky. This scene was recorded by the photographer. According to experts, the orbit height of the satellite is low when it is launched, and it can generally be observed after sunset or before sunrise. The "Star Chain" project is expected to send 12000 satellites into space, which experts say may affect astronomical observation.

According to foreign media newatlas, every "starlink" satellite is equipped with a sun visor, and they are controlled, so the impact on astronomers who are observing the night sky in detail is not so obvious. Spacex has launched more than 400 satellites to support a satellite constellation that will one day provide global broadband Internet access.

The surge of satellite technology and the increasing price of reaching low-earth orbit have made many people worry about the possible impact of "space traffic" on the night sky. With the emergence of giant satellite constellations, this issue is becoming more and more controversial.

The' Star Chain' giant satellite constellation is successfully becoming a reality, and one day it can provide high-speed and low-delay satellite broadband around the world. Of course, it is not ideal to let groups of bright satellites bomb long-exposure telescopes. A recent study published in the journal Astronomy and Astrophysics shows that the introduction of thousands of new satellites may have a significant adverse impact on ground-based celestial observation.
