GPS Navigation System Can Save You Gas and Money at the Pump

Have you ever wondered what a GPS Navigation system was and how it can be an important piece of technology for you and your family? Simply, a GPS navigation system is an electronic device that can pinpoint and determine one's exact location on earth, anywhere. GPS is the short form of Global Positioning System. This navigation system was first developed and implemented by the United States' Department of Defence, in an effort to out smart the enemy. The primary function of a GPS navigation system is to pinpoint its actual location on earth using the signals it intercepts from GPS satellites. To do this, the GPS navigation system must be able to locate and intercept signals from three or more GPS satellites. Once the signals are intercepted, GPS navigation use basic principles of mathematics called triangulation to compute its actual position.
