It may seem magical, but there is only science and technology. It's called Global Positioning System or GPS. I was the first time for them, while a soldier introduced. At that time the technology was new and often unreliable. It was more of an interesting toy, but I know where I was a map. But that was then and this is now.
You may have seen advertisements. Maybe someone had to show what he has. Maybe you have a friend or acquaintance, oftenshow your GPS and how they do.

The purpose of GPS is to show where in the world has to tell. Although not necessarily use, it would be nice to know how it works.
You've probably seen a globe in the classroom, when the places of the school and many others. You'll notice the horizontal and vertical lines on it. These are the latitude and longitude in degrees, minutes and seconds measured
The grid or matrix is created by vertical and horizontal linesthe Foundation for the Global Positioning System.
High in the sky are 24 GPS satellites in orbit around it, courtesy of Air Force. They are packed with electronics and software designed to help us know where we are at all times. That is, if we have a global positioning system at hand.
The satellites to know where all the time. I'm constantly emit radio beams that have received from ground stations. Similar to radar or sonar determines the positionthe time taken to reach the station.
Since it is known that people on the accuracy of the systems use atomic clocks to ensure timing is correct. The timing system technology combined with integrated, designed to correct errors, bed in a safe location.
A system consists of satellites, ground stations and the device. Together to create a very complex triangulation calculation. The results are that come with your position withhigh degree of accuracy. The GPS receiver is awaiting a signal from 4 satellites and provides you with your site.
This is a simplified overview of the Global Positioning System works. It 's more complex, but this is not necessary to understand how they can benefit. As you can see it is not magic, but you must agree that it is magic.
