In June 2020, the last global networking satellite of Beidou-3 was launched, and the deployment of the Beidou-3 global satellite navigation system constellation was fully completed half a year earlier than originally planned. In July 2020, the mainland officially announced the official opening of the Beidou-3 global satellite navigation system, which means that the application of the entire Beidou system has been oriented to the world, and the world can use China's Beidou system.
After the opening of the Beidou system, countries around the world are also accelerating cooperation with China, we know that 137 countries have signed cooperation agreements with the Beidou satellite navigation system, and with the continuous "diversification" of China's Beidou system.
By the end of 2020, the total output value of the mainland satellite navigation industry has exceeded 400 billion yuan, which means that China's satellite navigation industry has broken through the bottleneck of the market and gradually entered the scale, and it is initially estimated that by 2025, the total output value of China's Beidou industry will reach 1 trillion yuan.
However, when Beidou embarked on globalization, many people also faced many problems brought by Beidou, what Beidou dropped, Beidou charges, etc., so it was not used directly, indeed, there may be more people encountered, and even some people said that the Beidou system has no way to compare with GPS, what is the situation? Is it really not as good as GPS, not as good as people? We look at it step by step.
Directly do not use, Beidou still has the problem of dropping the line?
The problem of dropping the line has indeed occurred, but the root cause will be said later, here is the first look at the event. In April 2021, the disconnection of the dashcam of a large truck caused controversy because the truck driver in Hebei was given a penalty of 2,000 yuan after dropping the line, and the truck driver committed suicide.
Therefore, it caused a sensation for everyone, and directly focused on the problem of the Beidou system, first of all, we will not explain - whether it is a problem of Beidou. Everyone should know that even if the satellite navigation system is installed, it can be said that there are too many in the market, too many fake products, and it is easy to be misled.
And the car driving recorder of the truck driver who dropped the line this time is not a high-end "black technology", which can be seen everywhere on the market, which is a very ordinary product, and there are thousands of merchants engaged in the production and sales operation of such products in the market. Are you saying that the product installed by this truck driver is aimed at the channel?
No one knows about this. And through the mainland's "2020 Road Transport Vehicle Beidou Navigation Vehicle Terminal Product Quality Supervision and Random Inspection Results" shows that the mainland has sampled a total of 30 batches of products produced by 27 enterprises in 8 provinces (cities), and the quality sampling pass rate of vehicle terminals is only 70.4%, and it can be imagined how many problem products there are.
Of course, here we can all understand that the punishment of this incident may be a little strong for many people, and maybe they did not have 2,000 yuan for a trip. This time the fine was 2,000 yuan, so it also aroused the sympathy of many people. However, the mainland has regulations on the issue of fines.
And in different degrees, the penalties will also be increased. That's why such consequences have emerged, and even many people have abandoned Beidou after seeing this problem. Then we will discuss the key issues.
What is the reason for the drop of the Beidou line? Is it really inferior to people, not as good as GPS?
As we have introduced above, it has signed contracts with more than 100 countries, which is bound to be beidou, and even has the possibility of being better than GPS, and it is definitely too decisive not to use it directly.
Beidou satellite navigation system is the third most mature system after GPS and GLONASS, and it can be called "the weight of the country" in the mainland, mainly independently researched by the mainland. At least in the Chinese market, the use of GPS can be completely replaced.
Moreover, the strength of the mainland Beidou is not weak, and the positioning accuracy in North America, Africa and other places is about 5 meters, and in the Asia-Pacific region, it can be accurate to 2.5 to 3 meters. This is a precision in civilian use, and higher possibilities are possible.
Moreover, in the 9.3 military parade on the 70th anniversary of the victory of the War of Resistance Against Japanese Aggression, the mainland used beidou to make a speech, and the time error of the ground square team was only detected within 0.3 seconds, the distance error was within plus or minus 10 centimeters, and the air echelon was not bad in meters and seconds, which was quite strong.
Therefore, China's Beidou is still superior to GPS in some cases. That's so good? Why did Beidou still drop the line? In fact, this "pot" really should not be backed by Beidou, the mainland in the Beidou system layout, is real-time monitoring, any satellite problem can be immediately known, you said that if this truck driver is because of the Beidou system, it must be more than him alone in such a problem.
Therefore, judging from this place, it is definitely not a problem with the Beidou system. Therefore, dropping the line is not the problem of Beidou, mainly lies in the individual.
If someone has a dropped line problem when using Beidou, it is necessary to judge from multiple aspects, rather than the system problem that comes to mind first.
First, because we install a positioning system, vehicle supervision and service is mainly achieved through satellite positioning devices and satellite positioning system platforms, then is not their own built-in card problems, can not achieve data transmission.
Second, such as the software or hardware failure of the device, communication interruption (blind spot of the way or SIM card arrears), etc., there may also be a failure, resulting in the possibility of "disconnection".
Third, is it that you have walked to the signal blind spot, so you cannot transmit data, and there is a drop offline. If it is in an area with good communication and the disconnection is dropped for a long time, it can basically be speculated that the positioning device is faulty, the SIM card is in arrears or the human factor.
But on the whole, if everyone finds a drop in the line, they should think of it from themselves first, rather than thinking about the Problem of the Beidou System. Therefore, there is a 99% probability that Beidou will drop the line, not because of the system problem of mainland construction, but because of its own factors.
So such a good system, why do you have to charge for downloading navigation?
Indeed, people who encounter charges can say "too many", that is, many people have encountered, and even after the charges, there may still be a situation that cannot be used, this is not, everyone is angry, and then scolded their "bitterness" to the Beidou, what is the situation?
First of all, we have to make it clear that the Beidou satellite navigation system is not equal to beidou navigation, which is not a thing at all. Separately, the Beidou system we formed is a "big group", and Beidou navigation can only be said to be one of the products.
And everyone sees the so-called "Beidou map", "Beidou navigation", "Beidou positioning" and so on, in fact, it is not what APP officially developed by the mainland, and after the development of Beidou, the mainland has only announced a "free interface", there is no APPA, and these APP are developed by "third-party" companies.
Therefore, there is a situation where a fee of 20 yuan, a fee of 100 yuan, and so on can be used. But here it is clear to everyone that there is no direct official app in the mainland, and there is no charge for this statement.
And support Beidou is not through the APP to judge the explanation, whether your mobile phone supports Beidou, mainly depends on your mobile phone manufacturer, because it mainly depends on the hardware facilities of the mobile phone, emphasizing that there is a relationship with the hardware facilities of the mobile phone itself, not with what APP.
Therefore, the beidou related products that charge are actually deceiving everyone, and everyone should not be fooled. The US GPS is free, and Beidou is also free, which is the general situation.
summary
Beidou as a mainland independent research and development system, we should believe in their own strength, and in 2020, The director of the China Satellite Navigation System Management Office and the spokesman of the Beidou Satellite Navigation System, Ran Chengqi, is to illustrate that most smart phones support the Beidou function, and mobile phones that support beidou foundation enhancement high-precision applications have been listed.
For example: Huawei, Xiaomi, Samsung, Meizu, OPPO and many other mobile phones are selected and support beidou system. So, in fact, you may have used Beidou invisibly, but you don't know.
Everyone does not have to worry about what Beidou APP, once again, whether to support Beidou is to look at the "mobile phone", not to see the APP, and not to contribute money to the "third party".
