How to locate and track your vehicle anywhere in the world, in real time via satalite (Global Satalite Positioning System ) Is the tracking device real and working I need house advice and how to get one especially in Nigeria

The Global Positioning System is a satellite based navigation system made up of a network of satellites placed into orbit. It should work in any weather conditions, anywhere in the world, terrain and most importantly 24 hours a day.

The satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. The GPS receivers (You should be able to buy in naij) take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.
