What is a Portable GPS System?
The Global Positioning System, commonly known as GPS, is a network of satellites that determines a ground based userís specific latitude, longitude, and altitude. Portable GPS devices have become more integrated in our daily lives through navigation computers in cars to emergency locators in cellular phones. GPS locators are becoming increasingly popular for young and old alike and many new cars have a GPS locator or cheap GPS system built in
Purchasing a GPS System
There are many different types of cheap GPS units today. You have your handheld GPS locator, which is a portable GPS unit, or you have your stationary GPS in-car navigation system. You can even purchase a stand-alone USB GPS receiver, which can plug into your computer and can be used with GPS compliant software (such as mapping software; some receivers may come already with software) - the most popular standard for GPS receivers is the NMEA-0183 standard.
