There are GPS, Compass why?



March 30, 2015, China successfully launch a Beidou navigation satellite, which is the first of 17 Beidou navigation satellite launch, the successful launch marks the beginning of the Beidou navigation system run by the regional to the global network.

In fact, as early as 2012, the Beidou navigation will officially start the Asia-Pacific region to provide most services, but many people still are not familiar with it, and today we take a look after the Beidou satellite navigation system is fully completed, in the end what the application ? In addition, there have been very easy to use GPS global satellite positioning system, why spend huge sums of money to build one?

A wide variety of applications

Say global satellite navigation dim, it is really three days and nights would not be enough. There are hundreds of satellite navigation applications, which affects almost all aspects of modern society. Moreover, the number of applications is growing. In short, the satellite navigation in the end to what use, it all depends on human imagination.

Like the sun, everyone worldwide equitable access. The global satellite navigation signals, like the sun, the air, like, all the time, these signals from heaven, filled in around us, anyone can get, and will not be the same as the phone signal, the more people appear to use signal in the case of the worse. This is well understood, like a broadcast signal, the number of radios without the slightest effect on the strength of the broadcast signal.

Whenever and wherever, we can carry out positioning and navigation, no matter you are a man, or a sheep, or also a robot, the signal can be used global satellite navigation system, so the applications of satellite navigation is really varied, after another, all the applications are too difficult to enumerate, but we can give a few interesting applications, so that we experience what the power of satellite navigation:

1. Reduce Accidents

According to the survey, 40 percent of fatal car accidents caused by speeding. Although many on the road to install a camera to monitor the driver, to prevent them from speeding, but you can not have cameras installed on all roads, because such spending is too high. Therefore, where there is no monitoring, speeding often bring a lot of vicious traffic accidents.

In addition to satellite navigation and positioning and navigation to better measure the speed of the vehicle, so long as an integrated navigation system in the car all the factory, such as our Beidou navigation system, you can at any time with full control over the speed of any vehicle. Thus, the phenomenon will greatly reduce speeding, traffic accidents will be reduced.

Also, for safety reasons, traffic law carts on the highway can not be left to walk, but always repeated violations carts. The same reason, you can not install cameras to monitor all on long highway. However, if installed on all major car factory there Beidou navigation terminal, we can always monitor the actual traveling route of the vehicle.

2. Grazing help you

Grazing is a very hard thing, you have to follow the flocks or herds Run away run, save a little way point force is to have a collie, collie let run errands for you, but you still have to follow. If you wear a small device on each sheep ears, then you can while drinking coffee at home while the sheep.

First, a small device that can be built on the sheep ear Compass terminal, which allows you to always get the exact position of each sheep on your computer. In addition, this little device utilizes solar power, can make some noises, such as shepherd's cries, Shepherd calls, car sound like. By some sheep flock to play the sound, you can make very obedient flock in accordance with the owner's instructions forward, turn or U-turn. If a sheep "dead pig is not afraid to open water hot," the sound is not cold, you can also make this little device emits a slight electric shock to stimulate the movement of sheep.

More, in fact, to cite only a few unusual examples. In fact, satellite navigation has been in agriculture, aviation, the environment, maritime transport, public safety and disaster relief, railways, space, surveying and drawing on the timing and there are plenty of applications.

More important application is in defense, almost all aircraft and missile navigation and positioning needs to function, loss of location information, may be lost aircraft, missiles do not know where the shooting. In an example of the Big Dipper, 2020, the Beidou satellite global navigation feature, enabling our combat efficiency increased by 100 to 1,000 times, cost-effective operations increased by 10 to 50 times, which will greatly enhance our defense capabilities.

Beidou navigation What is the significance?

Countless people in private cars or mobile phones and other devices using free GPS navigation, the user experience is very good, people mention it first thought GPS navigation, which leads to a lot of people do not know China is also a set of autonomous navigation and positioning system. And I know that the Big Dipper, also puzzled with GPS can not it do? Duplication, really necessary?

Through a variety of applications described above, we now know that the answer is beyond doubt. It's like, others to provide air to maintain your existence, does not mean you should not have their own air. Because, you must not lose control of their own lives!

GPS navigation system is the United States, the United States may be needed to close an area navigation service. If one day, we have sinned against the United States, they closed the GPS service, and therefore of numerous industry will be greatly affected. If you are a local've never been, in the car navigation guidance, suddenly, navigation did not, how do you do it?

In fact, after the completion of GPS, the United States put the GPS signal is divided into two types of standards for civil and military standards.

Since the civil standard positioning service does not require any authorization, you can use any, so the United States worried that the enemy made out with his sword to attack themselves, so in the civilian signal artificially added error to reduce the accuracy of the positioning accuracy in about 100 and military precision of 10 meters or less.

Until 2000, the US was canceled interference to civil signals. Because the United States through a system update, it has been able to achieve in any wartime close the GPS signal in an area, the other is, which is to enable GPS navigation systems continue to have a global monopoly.

GPS really free?

As long as there is a smart phone, anyone can search for and receive signals to gps positioning and navigation, seemingly free to use, it is not. Cell phones have gps modules, each producing a gps module manufacturers are required to pay the United States in order to obtain authorization. There gps module on your phone, the phone costs will increase, ultimately, consumers still pay.

So, after the Beidou global navigation fully completed, it will enable manufacturers to benefit domestic navigation terminal to achieve corner overtaking.

As a big country, we must have its own global satellite navigation system, which is the Big Dipper! It is China's Compass, Compass will also be the world!
