GPS (Global Positioning System) system in automobile is very practice. You can see map and direction where ever you drive your car. GPS (Global Positioning System) is a satellite navigation system developed by the United States Department of Defence. GPS allows us to know our geographical position (latitude, longitude, and altitude above sea level). So wherever we are on this earth, we can know exactly where we stand.
GPS working system can be divided several points, namely the first at the controls, each satellite can be a bit beyond the orbit, so that this part of the satellite orbit track, location, altitude, and speed. Extract the satellite signals received by the control section, corrected, and sent back to the satellite. Correction precise location data from the satellite ephemeris data is called, which will send it to our navigation equipment and in this case is GPS receiver installed on our car. By integrating the car real time position with map, we can see the position our car when we driving.
The second part of space, this section consists of a collection of satellites in earth orbit, about 12,000 miles above the earth's surface. Collection of satellites is arranged so that the navigation tool in our automobile at any time can receive signals from at least four satellites. These satellite signals can pass through clouds, glass, or plastic, but it can not pass through buildings or mountains. That is way when we driving in a clear space, our car can receive signals and from these satellites.
