What happened to the star chain in the sky?
The Star Chain Project is a huge global satellite constellation network initiated by Space Exploration Technology Company, which aims to provide Internet connection services for people on earth. These satellites run in low-earth orbit and can be observed with the naked eye under special conditions. So the strange phenomenon that these bright spots are connected in a line is probably caused by the satellite chain.
Although companies like Space Exploration Technology have publicly announced their satellite plans, this phenomenon is still novel and mysterious to most people. Moreover, because most people have limited knowledge of astronomy, it is easy to mistake these satellite chains for other UFOs or supernatural phenomena.
The difference between star chain and Beidou:
1, Star Link is a global communication system in the United States. It is planned to realize high-speed communication with tens of thousands of small satellites, but the orbit is low, the anti-interference performance is weak and the practicability is not strong.
2. Beidou is a self-built satellite navigation system in China, with multi-orbit satellites as the main body, which can carry out more accurate positioning and instant communication.
3. Beidou mainly provides navigation and positioning services, and has certain short message communication function, which is suitable for emergency communication with low real-time requirements.
4. Satellite link is a broadband Internet connection, which supports low-delay broadband and can carry out high-speed communication, but its running track has low anti-interference performance and is not practical.
