GPS uses a series of satellites. It needs at least three satellites, but usually talks to as many as it can. It bounces a signal to each satellite and can tell how far away it is from each by the time it takes for the signal to return. Often indoors or in steep canyons they don't work because they can't get a clear view of at least three satellites.
By knowing the distance to three or more satellites, the GPS receiver can pinpoint exactly where it's located (called triangulation).
People use GPS for almost anything you can imagine related to either figuring out where they need to go or tracking where they have been. Geocaching is a game where people hide little boxes with trinkets or a log book inside, and post the coordinates on a website, then people find the boxes and exchange something they bring for something inside the box. You can use GPS for directions in your car, to keep from getting lost on a hike by tracking where you've walked so far, etc. Some people use a GPS attached to their digital camera to record where they were when they took a picture. The possibilities are endless
