Devices That Support GPS Navigation
GPS Navigation, or Global Positioning System navigation, determines the location of the GPS device on or just above the planet Earth. There are many devices these days that feature GPS navigation, ranging from cars, cell phones, portable computers and compasses. Where ancient mariners had to use the stars to navigate, we can use devices among the stars to tell us where we are.
As technology has evolved and advanced, however, so, too, have navigation tools. Today, the majority of cell phones, cars, computers, and other electronic devices contain global positioning satellite, or GPS devices or capability. Some GPS equipment uses technology similar to that of an ordinary radio receiver. However, instead of picking up sound waves like a radio receiver does, GPS technology involves the use of a microchip that picks up signals broadcast from satellites that are orbiting around the earth. In order to pinpoint and display a map of a particular location, GPS devices must receive information from a number of different satellites, through a process called triangulation.
GPS navigation equipment works in different ways. Some devices rely on technology similar to that of an ordinary radio receiver. However, instead of picking up sound waves, the microchip in the device uses as many of the hundreds of satellites orbiting the earth to receive the signals and triangulate them so that a specific location can be pinpointed.
GPS navigation equipment can be a great asset to a traveler; however, there may still be times when an ordinary printed map and/or a cell phone with basic GPS navigation capability may be needed. If necessary, you can pinpoint your position on the printed map, and use it to get back to a main road, or, if you have the phone number of someone at the endpoint of your trip, you can call and see if they can give directions.
There are PocketPCs with GPS navigation systems incorporated into their design. These PocketPCs are some of the most intelligent uses of a GPS navigation system for many people. Along with software for the GPS navigation systems, you are able to see where you are and also what is around you through satellite photography. This combined technology can be extremely helpful if you become lost or your car breaks down in a remote area.
Consumers can choose from many different brands of GPS navigation devices. Examples of brands include TomTom, OnStar, and Garmin. Depending on which brand is chosen, the GPS navigation devices often come with live support.
