The Global Positioning System (GPS) was funded, developed and controlled by the US Department of Defense. Since the late seventies, GPS has become an important aid to navigation around the world. Initially designed for the US military, GPS became publicly available years later and it is now considered an important feature in lots of consumer products.

Built-in GPS chips are hooked into a system of satellites which allows accuracy to the meter in determining the position of whatever has a GPS Chip. They can be used to track kids, pets, cattle, property, and even yourself. And best of all, you'll forget its even there because its literally built-in!

If you enjoy hiking or long-distance running, the built-in GPS chip can track how far you went, exactly what you route was, and, mopst importantly, where you are if you get lost.Commercial GPS portable devices are now available in an amazing variety of applications besides stand alone receivers. They are incorporated into PDAs, wristwatches, and cell phones. And of course, there are portable GPS receivers for automobiles, motorcycles, and boats.

Commercial GPS portable devices are now available in an amazing variety of applications besides stand alone receivers. They are incorporated into PDAs, wristwatches, and cell phones. And of course, there are portable GPS receivers for automobiles, motorcycles, and boats.

One great appeal of many portable GPPS devices is their multi-functionality. A wristwatch with GPS capability, for example, is a great tool for those who enjoy outdoor pursuits like hiking, fishing, and camping; it eliminates the need for inconvenient maps. Having a GPS portable device in your PDA will be a great way to help you find your way around strange cities or find alternate routes when traffic is moving against you.

Although there are many benefits in using GPS cell phones (telefone celular), there are some people who are concerned about the violation of personal privacy. Since the US Congress has not authorized location tracking without actual evidence of wrongdoing, there have been court hearings which have not approved the requests of government agencies in obtaining the cell phone GPS tracking information for suspects or ordinary citizens.
