The capability to know where you are, where you want to be, and how to get there was previously best found by using a paper map. If you were travelling in your car then there is a good chance you used either an atlas or one of those big tri-folded maps which actually weren't much help as you are attempting to drive. Fortunately finding your way in the world nowadays is easier thanks to the Global Positioning System (GPS) and the varied types of GPS gadgets that use it.
If you are wondering how these GPS devices do what they do then read on. The Global Positioning System was designed and applied by the United States Department of Defense when it started its first GPS satellite way back in 1978. Today there are 24 satellites in the GPS network that are the cornerstone of the entire system.
There are a number of varied types of GPS devices that are designed to take advantage of this constellation of satellites. GPS mapping devices are utilized to collect points and any information attached to those points for mapping function. In fact these devices have been utilized for years to collect the data that creates the maps and mapping features used by different GPS navigating systems.
Which brings us to the very famous user GPS device: the GPS navigating system. The most familiar of these is the in-car GPS unit that shows you map of where you are going and informs you through voice directions how to get there. These GPS devices are either mounted in the cars dash or are portable and can be moved between cars.
Some navigational devices offer a feature where you can locate restaurants, shopping, hospitals, and hotels regardless of where you are; this can be incredibly useful when looking for services in a town with which you are new. The tinier versions of these navigational gadgets are portable devices that can be used by backpackers, hunters, and other outdoor enthusiasts.
These kinds of GPS devices will keep track of where you are, leave a breadcrumb trail of where you've been, and will guide you to where you want to go. Many of these units additionally include built in cameras and voice recorders, allowing you to keep a list of your trips. - 22787
