GPS navigation systems are navigation and accurate positioning devices. Created by the Department of Defense in the early 1970s, GPS was primarily created to assist soldiers and military vehicles, ships and planes in precisely establishing their positions anywhere in the world. These days, the purposes of GPS navigation systems are both scientific and commercial. In the commercial world, GPS is utilized as a navigation and locating device in boats, airplanes and other vehicles. It is also extremely useful for hiking, kayaking and fishing. In the scientific world, GPS is quite essential in earth sciences. Meteorologists utilize it for weather forecasting and global climate studies. Geologists can also utilize GPS navigation when studying earthquake events and potential activities.
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.

The Garmin Nuvi 350 model employs NAVTEQ mapping features in addition to carrying a relatively low price tag.
