If the United States turns off GPS signals, will any country become "blind"

The answer is yes, there are not a few countries that have become blind.

GPS is a new generation of satellite positioning system developed by the United States in 1970s. After more than 20 years of research, it cost more than 30 billion dollars and was finally completed in 1994. It can be said that the technology of the United States is still leading in the world, and many countries use the American GPS global positioning system. GPS plays a key role in travel navigation, smart payment and service enjoyment. In the military, it also has extremely important applications, especially in missile guidance.

Once the GPS signal is lost, it will have very serious consequences. Nowadays, many countries use GPS in the positioning system of missiles, so once the satellite system is turned off in the United States, most missiles are no different from fireworks and firecrackers, and there is no accuracy at all. This will be a great threat to many countries, weapons can not be used, and it is a great threat to homeland security.

But only two countries in the world are not disturbed by it, namely China and Russian. Even if the United States does shut down the system one day, it will not have any impact on China and Russia, because we are not using the American positioning system now, but our own positioning system.

The global satellite navigation system established by China and Russia based on their respective technologies provides a more complete system guarantee for the national armed forces, improves the national defense level, and holds the right to speak on missile guidance capability in their own hands. China Beidou navigation is gradually improving, and soon, it will completely replace GPS and be used nationwide.
