GPS navigation systems are devices that provide navigation and accurate positioning information. The Department of Defense created these devices in the early 1970’s. They were created mainly to assist soldiers and military vehicles, ships and planes in establishing positions throughout the world. Today, the navigation systems are used both commercially and scientifically. In the retail world, GPS is used in cars, boats and other vehicles. The devices are also helpful for hiking, fishing and canoeing. The devices provide the user with accurate information and directions. In the scientific community, GPS is essential in the earth sciences. The devices are used by meteorologists to forecast the weather and study the climate. They are also used by geologists to study earthquakes and potential seismic activity.

GPS navigation systems are now being used by more and more civilians. They have proven to be extremely useful in many different situations. They now come in several different designs, functions and features.
