What is GPS?
GPS stands for Global Positioning System and offers a convenient solution to the confusing maps and directions in today's busy world. A GPS device uses a built-in receiver to acquire information from one of 30 GPS network satellites orbiting the Earth at spans of 12 hours. Once a GPS receives this data, it is able to pinpoint your location and calculate speed, direction and elevation.
Your GPS system then cross-references your information with map files stored within the unit. The device is then ready to guide you to your destination marked on the same map. All of this is typically communicated to you through the combination of voice guidance and video data via an LCD screen. Think of your GPS as your own personal tour guide as you navigate your way through a hectic lifestyle!
