Having a GPS without knowing their role? The matter should be avoided, because if we have GPS we also need to know what are the uses of GPS, here are some uses GPS
vehicle tracking
Other uses are as a GPS vehicle tracker, with Bant
uan GPS vehicle owner / manager of a car rental service can find out there anywhere vehicle / asset moving in today.
Navigation
Many also used as a GPS navigation tool such as a compass. Several types of vehicles have been equipped with GPS for navigation aids by adding a map, so it can be used to guide motorists know the path that should be selected to achieve the desired objectives.
Military
GPS is used for the purposes of war, such as guided towards a bomb, or know where the troops were. In this way we can find friends and opponents to avoid any targets or determine the movement of troops.

earthquake monitoring
Even today, GPS with high accuracy can be used to monitor the movement of land, which ordenya only mm a year. Monitoring of ground motion are useful for estimating the earthquake, both volcanic or tectonic movements.
Geographic Information Systems
For the purposes of Geographic Information Systems, GPS is often also involved in creating the map, such as measuring the distance of the border or as a reference measurement.
How does GPS work ???
How GPS works, we can divide into five stages or the GPS concept works as follows:
1. The basis of GPS is the concept of triangulation from several satellites. Triangulation method is a method of determining the point of using the principles of the triangle
2. To make the process of triangulation, GPS receiver measures the distance on the basis of the time required by a radio signal to travel from the transmitter on a satellite to our GPS receiver.
3. To measure travel time, GPS requires a highly accurate time which is achieved by doing some tricks or ways.
4. Along with the distance, we also need to know exactly where the position of the GPS satellites are located. The key is to know the height of the GPS satellite orbit and monitor the GPS satellites in the orbital.
5. Finally, you have to correct for any delay in GPS radio signals after passing through layers trip Atmospere
Behind it all, in fact the basic idea of ​​the calculation using the GPS position is that we use the position of GPS satellites are in space Space used as a reference point for determining the position of a point on the earth. With highly accurate measurement of the distance of at least 3 GPS satellites we can position anywhere on earth with a method of triangulation.
GPS systems
GPS satellites circle the earth 2x a day
These satellites transmit signals to earth
Signal is used to calculate the time posisiGPS distinguish transmitted to calculate the position
This is calculated as the distance of several GPS satellites to calculate the position of the earth and its surface, including exosphere
Basic GPS Work
GPS must have at least three satellites to calculate a 2D position and movement.
With four satellites, GPS we can calculate the position of the 3D position (latitude, longitude and altitude).
With the position information, the GPS can calculate other data such as speed, direction, trajectory, distance, distance to destination, sunrise and sunset and others
