What is the satellite link for? What is the function of satellite chain?

1, the satellite link can provide low-cost internet connection services on a global scale.

Before the United States launched the satellite chain, the satellite chain crossed the sky like a "Galaxy train", which was recorded by photographers. According to experts, the orbit height of the satellite chain is low when it is just launched, and it can generally be observed when it transits some time 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 controlled, so its influence on astronomers who are observing the night sky in detail is not so obvious. Space Exploration Technologies has launched more than 400 satellites to support a constellation of satellites that will one day provide global broadband Internet access.

4. With the rapid improvement of satellite technology and the increasing price of reaching low earth orbit (LEO), many people (especially scientific people) are worried 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.

5. The satellite chain giant satellite constellation is becoming a reality smoothly, and one day it can provide high-speed and low-delay satellite broadband all over the world. Of course, it is not ideal to let groups of bright satellites bomb the observation of 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 major adverse impact on ground-based celestial observation.
