Introduction
- A GPS, or global positioning system, is a network of satellites that is used as the basis of a navigation system. There are GPS receivers that are designed for automobiles as well as handheld models.
Step 1: What is GPS?
- The GPS was developed by the U.S. Department of Defense for military use. It is a worldwide network of satellites and ground stations which send signals to a receiver that processes the data, and determines location accurately to within a few yards.
Step 2: Automobile GPS
- All GPS receivers designed for automobiles can calculate location and determine directions to a given location. Many have additional features, however, and depending on your model you may be able to use your GPS to:
- Avoid traffic jams. Many models now have the potential to process real time traffic data, altering directions accordingly. If your model has this capability, you will usually need to subscribe to the traffic data at an additional fee.
- Locate points of interest, such as the nearest gas station, restaurant, or tourist attractions.
Step 3: Handheld GPS
- A handheld GPS is based on the same technology as the automobile GPS, but is used primarily by hikers. the features found on a handheld GPS include:
- The ability to pinpoint your exact location at any time.
- Determine the distance and direction to a given point.
- Record where you parked your car.
- Automatically record the route you're hiking, so you can return by the same path.
- Record waypoints along your route.
- Some devices also have a built in compass, for traditional navigation, so you can switch back and forth between methods.
