Do you still need to pay the United States after the Beidou system runs?

Beidou satellite navigation system has completed the global networking, which can be said to completely get rid of the dependence on American GPS satellite navigation system. Speaking of cost, the GPS system in the United States is free for civilian use, military use, allies and non-allies. The GPS system used in our country belongs to the civil scope, and the military scope is not open to the other side. Needless to say, American imperialists will never die.

There are many reasons why GPS satellite navigation system is free. Small fans only say one, and one is dominant. It's like Microsoft's Windows system. Although there is a charge, you can install a system to crack it. Although Microsoft shouted fiercely, it didn't see what to do. Why? Look at the current computer desktop operating system. Windows is unique, and no other system can develop except Apple. Because there is a mature Windows system that has been developed for decades, who is willing to spend huge sums of money and time to develop a new system?

In this way, it is very difficult to develop a new system and get rid of Windows. The same is true of GPS satellite navigation system. Small countries naturally have no strength to research and develop. Big countries have ready-made GPS for free, and several are willing to spend huge sums of money to build satellite systems! Take European countries for example. Dozens of countries have joined forces to build Galileo satellite navigation system. If a European country is really allowed to build it alone, bye. Due to the hostile relationship with the United States, Russia had to build the GLONASS satellite system, and the money spent was heartbreaking for Russia.

Why should we build Beidou system for free GPS? To avoid getting stuck in the neck, of course. If you care about national affairs, you should still remember the military exercise in those days. The United States suddenly shut down our GPS service, causing the missile to lose its target. 1, the national security GPS system is American, and they have absolute control. Although we can use it for free, people can close it at any time. For example, one of our big ships suddenly loses GPS navigation at this time, or the navigation accuracy in the United States is greatly reduced, and the ship becomes a headless fly. This kind of thing has happened before.

2. Where do I charge for 2.GPS? Although it is free to use, it needs hardware to accept GPS signals, such as GPS chips and GPS software fees. As long as you build your own satellite navigation system, you can make your own decisions, and you are not afraid of getting stuck, especially in the military. After the success of Beidou navigation system in China, it is accurate to locate the civil signal within 10 meter, and it can reach within 5 meters in the Asia-Pacific region. If it is strengthened with the ground, it can achieve centimeter-level positioning.

By the way, recently, many people have said that they have to pay the fees in 20 yuan. This is an operational error. As long as your mobile phone chip supports Beidou, when you use Baidu or Gaode map navigation, you are already using Beidou navigation system. There is no need to install that kind of charging software. Recently, many people ask about the satellite overhead. Small fans use Cellular-Z software, which can clearly show which navigation systems and several satellites are overhead.
