What is the significance of Beidou navigation when mobile phones have GPS?

On March 30, 2015, my country successfully launched a Beidou navigation satellite. This was the 17th Beidou launched by our country. The successful launch of the navigation satellite marks the beginning of the Beidou navigation system's transition from regional operation to global networking.

In fact, as early as 2012, Beidou Navigation began to officially provide services to most parts of the Asia-Pacific region, but many people are still unfamiliar with it. Today we will take a look at it. The Beidou Satellite Navigation System has been fully completed. After that, what applications will there be? In addition, there is already a very easy-to-use GPS global satellite positioning system, why should we spend huge sums of money to build another one?

A variety of applications< /strong>

To talk about the usefulness of global satellite navigation, it would take me three days and three nights to explain. Satellite navigation has hundreds of applications that influence almost every aspect of modern society. Moreover, the number of applications continues to increase. In a word, the usefulness of satellite navigation depends entirely on human imagination.

Just like sunshine, everyone in the world can get it fairly. The signals of global satellite navigation are just like sunlight and air. Every moment, these signals fall from the sky and permeate around us. Anyone can get them, and they will never be like mobile phone signals. The more people use the signals, the more signals they appear. The worse the situation becomes. This is easy to understand. Just like a broadcast signal, the number of radios has no impact on the strength of the broadcast signal.

No matter when and where, we can position and navigate. Regardless of whether you are a person, a sheep, or a robot, you can use the signals of the global satellite navigation system, so The applications of satellite navigation are really diverse and emerge in endlessly. It is too difficult to list all the applications, but we can list a few interesting applications to let everyone experience the power of satellite navigation:

1. Reduce traffic accidents

According to surveys, 40% of fatal car accidents are caused by speeding. Although cameras are installed on many roads to monitor drivers to prevent them from speeding, you cannot install cameras on all roads because of such waste. The price is too high. Therefore, in places where there is no monitoring, speeding often leads to many vicious traffic accidents.

In addition to positioning and navigation, satellite navigation can also measure the speed of vehicles, so as long as it is installed at the factory. Vehicles equipped with a unified navigation system, such as our Beidou navigation system, can fully control the driving speed of any vehicle at any time. In this way, speeding will be greatly reduced and traffic accidents will also be reduced.

Also, for safety reasons, the traffic law stipulates that large vehicles cannot drive on the left side of the highway, but violations of large vehicles are always prohibited for the same reason. You cannot install cameras for monitoring on all long highways. Beidou navigation terminals are installed on all factory trucks, and we can monitor the actual driving route of the vehicle at any time

2. Help you herd

Herding is a very hard job. You have to run and run with the sheep or cattle. A way to save a little effort is to have a shepherd dog and let the shepherd dog run for you. Running errands, but you still have to follow.If you wear a small device on each sheep's ear, you can shepherd the sheep at home while drinking coffee.

First of all, the small device on the sheep's ear can have a built-in Beidou terminal, which allows you to obtain the accurate position of each sheep on your computer at any time. In addition, this small device is powered by solar energy and can emit some sounds, such as the shouts of shepherds, the barking of sheepdogs, the sound of cars, etc. By playing sounds to certain sheep in the flock, the sheep can be made to follow the owner's instructions to move forward, turn, or turn around. If a certain sheep is "not afraid of boiling water" and is not interested in the sound, this small device can also be used to send out tiny electric shocks to stimulate the sheep's movement.

The above are actually just a few uncommon examples. In fact, satellite navigation already has rich applications in agriculture, aviation, environment, maritime transportation, public safety and disaster relief, railways, space, surveying and mapping, and timing.

A more important application is in national defense. Almost all fighters and missiles require navigation and positioning functions. Without location information, fighters may get lost and missiles may not know where to shoot. Take my country's Beidou as an example. In 2020, after Beidou realizes the global satellite navigation function, it will increase our country's combat effectiveness by 100 to 1,000 times and increase the combat cost-effectiveness by 10 to 50 times. This will undoubtedly greatly improve our country's national defense capabilities.

What is the significance of Beidou navigation?

Countless people use it for free in private cars or mobile phones and other devices Using GPS navigation, the user experience is very good. When people mention navigation, they first think of GPS. This leads to many people not knowing that our country also has an independent navigation and positioning system. And those who know Beidou are also confused. Isn’t it enough to have GPS? Is it really necessary to repeat the construction?

Through the various applications introduced above, we now know that the answer is undoubtedly of. It's like just because someone else provides you with air to survive, it doesn't mean you shouldn't have your own air. Because you must never lose control of your life!

GPS is the navigation system of the United States. The United States can shut down navigation services in a certain area as needed. If one day we offend the United States and they shut down GPS services, countless industries in our country will be greatly affected. If you are driving in a place you have never been to before, and suddenly the navigation disappears, what should you do?

In fact, after the completion of GPS, the United States divided the GPS signal. There are two categories: civilian standards and military standards.

Since civilian standard positioning services do not require any authorization and can be used at will, the United States is worried that the enemy will use a sword of its own making to attack itself, so it artificially adds errors to civilian signals to reduce accuracy. degree, so that the positioning accuracy is about 100 meters; while the military accuracy is less than 10 meters.

It was not until 2000 that the United States canceled interference with civilian signals. Because the United States has been able to arbitrarily shut down the GPS signal in a certain area during wartime through system updates. In addition, this is to allow the GPS navigation system to continue to have a global monopoly.

Is GPS really free?

Anyone with a smartphone can search for and receive GPS signals for positioning and navigation. It looks like it’s free to use, but it’s not. There is a GPS module in the mobile phone, and every time a manufacturer produces a GPS module, it needs to pay a fee to the United States to obtain authorization. After the GPS module is installed on the mobile phone, the cost of the mobile phone will increase. In the end, consumers will pay the bill.

Therefore, after my country’s Beidou Global Navigation is fully completed, it will benefit domestic navigation terminal manufacturers and enable overtaking in corners. As a big country, we must have our own global satellite navigation system, which is Beidou! It is not only China’s Beidou, but also the world’s Beidou!
