The Global Positioning System (GPS) is a space-based radio-navigation system consisting of a constellation of satellites and a network of ground stations used for monitoring and control. Garmin hand-held aviation GPS have all the features of the panel mounted units. They are fully equipped with Jeppesen databases, and background land mapping.
The latest GPS have log-book compatible features, to make flight reporting even easier. The units are sold with a free upgrade of the Jeppesen database (within 90 days of purchase). All aviation handhelds can be used in conjunction with Garmin Mapsource digital mapping which allows the GPS user to plan and create points and routes on a computer, using the detailed map background. Then simply load those points in to the Garmin GPS unit.
