Western navigation satellites are paralyzed in a large area. Why did China's Beidou escape?

According to American media reports, Galileo satellite navigation system, the world's fourth largest satellite navigation system jointly developed by many European countries, suffered a serious failure. Twenty-two satellites completely lost contact, and the whole system collapsed, unable to provide services for users. And this time, the problem of system paralysis is difficult to solve, and Galileo officials can't estimate when the service will be resumed. This also makes this system with weak sense of existence become the focus of attention recently. Galileo is a relatively independent but imperfect satellite navigation system in the world. Before Galileo, there were the largest and most mature GPS satellite positioning system networks in the United States, GLONASS satellite navigation system in Russia and Beidou navigation system in China. However, the satellite navigation systems after Galileo were all regional satellite navigation systems developed by some small countries themselves, which could not provide global positioning services.

It is understood that it takes at least 22 satellites to complete the global satellite positioning service, and most countries cannot launch such a large number of navigation satellites, so only four navigation systems in the world can be recognized as global satellite navigation systems. Galileo system is one of the least satellites. This time, the satellite is out of control, which is even worse.

Now Beidou system has already surpassed Galileo system to become the world's top satellite navigation system, and its original communication function is not even available in American GPS system. Looking at the Galileo system now, it seems that we should thank the arrogance of Europeans and finally did not join this "cheating" system. It is said that the cause of the large-scale failure of the navigation system is the failure of an accurate timing device developed in Italy, which was used in the system. In the end, the system can't time correctly, and finally it loses its positioning and navigation ability. In addition to Galileo satellite, not long ago, Russia's GLONASS system also failed, which also brought a lot of trouble to Russia.

GLONASS-1 * * has a total of 27 navigation satellites in orbit. However, due to its long research and development cycle, 16 satellites have been out of service, so the failures continue. The previous failures have greatly reduced its positioning accuracy and even affected the military frequency band. It is impossible for Russia to solve this problem in a short time, so it can only launch a new satellite as soon as possible to replace the failed satellite. However, the components in Russia's navigation satellite system use a lot of equipment provided by the West, so if they are used in Russia,

According to the report, Galileo system is a system jointly developed by many countries. At one time, China also hoped for joint development and was willing to provide financial support. However, arrogant Europeans are only willing to provide us with the right to use the system after it is completed, and do not intend to transfer more technology. This made us see that Europeans lacked sincerity, so they began to develop the Beidou system themselves.

On the other hand, Beidou system, its key components are made in China, which also allows me to master the fate of Beidou. No matter what happens, it will not be stuck by the west. At present, the demand of satellite navigation system is becoming more and more complicated. Although the Beidou system was successfully networked, compared with GPS, the number of satellites did not reach several. In the future, Beidou system will continue to launch more satellites to provide more accurate positioning services for China.
