, China couldn’t even make nylon socks, but now you can see things made in China all over the world. As Chinese, we are proud and proud of our motherland, especially Huawei’s 5G The breakthrough in the field has shocked the world. However, because Huawei’s research has affected the interests of the United States, the United States has begun to do everything possible to suppress and sanction Huawei’s development, and said that US companies will no longer provide Huawei with chips necessary for 5G mobile phones, because China has not been able to lithography The machine was manufactured, so Huawei was in trouble for a while. Such things have actually happened before.
The Yinhe incident that occurred in 1993 was a huge shame in the eyes of many people. At that time, only the GPS of the United States could achieve global navigation and positioning. They excused that there were contraband on the Yinhe to check and intercepted the Yinhe GPS. The signal caused the Yinhe to lose contact with the motherland. Later, China made up its mind to integrate its own system as soon as possible, so that such humiliation would not repeat itself.
Later, through the efforts of past generations of scientific researchers, my country's Beidou-3 was officially opened in 2020. my country's Beidou and the US GPS are both open to the world, and the accuracy and other aspects of performance are not bad. , But when we take out the phone, we will find that the GPS is still displayed. Why does Beidou have achieved global coverage and we still need to use GPS? The answer is actually unexpected.
First of all, the Beidou system is still relatively new, and the total running time is not long enough. my country has no previous experience in this area, so we need to slowly make up for and improve the shortcomings of Beidou. Although we have controlled the error to the minimum range, there is still a certain gap compared to GPS. We need to spend more time to build it.
actually does not work if you want to replace the GPS with Beidou, because the GPS system is more complete and better. If you only use Beidou, it may not be so stable, so we still need GPS now, but it depends on It is indeed not as strong as before. It can barely be maintained if it is completely separated from GPS, but now we do not need to do so.
and for a long time we only have GPS available. Therefore, in many people’s minds GPS is equivalent to the synonym for navigation and positioning system. When it comes to positioning, our first reaction is them, so many mobile phones are broadcasting. When I still use this name. The reason is that Beidou's popularity is much lower than we thought. Many people abroad still only know GPS. This is really surprising.
In fact, many mobile phones are now used together with several sets of navigation systems, in order to further ensure accuracy, so that the error can be reduced to a small amount. Thinking of the things that happened with the United States in the past, many people in China must think Immediately abandon the use of GPS, but at least this is not possible for now. Did you guess the reason? Although it may be surprising, there is no way.
But the emergence of Beidou still brings some new energy to our country, and its appearance also means that we have broken the blockade in this field. In the future, we will be able to be in the same position as the United States in more places, and at the same time we I also hope that Huawei can get out of trouble as soon as possible and get updated development.
