What is GPS?

The Global Positioning System (GPS) consists of 24 satellites orbiting the earth at 12,000 miles (Figure courtesy of Garmin International)

GPS stands for Global Positioning System, a satellite navigation system initiated by the U.S. government in 1978 and today made up of a network of 24 satellites orbiting at 12,000 miles above. GPS was originally intended for U.S. military applications, but in the 1980s, the U.S. government made the system available for civilian use. Other than the cost of purchasing your GPS and accessories, use of a GPS is free -- there are no monthly subscription fees or setup charges. Nor do you need a license to operate a GPS. Your GPS will work anywhere you travel in the world, under any weather conditions, every day of the year.

Your GPS unit (also called receiver, system, or device) receives signals from the satellite to calculate your precise position on the earths surface. With signals from three satellites, your GPS can calculate your latitude and longitude. With four or more satellites, it can also calculate your altitude. Your GPS can also calculate your speed, direction of travel, distance traveled, local sunrise/sunset, and even predict local tides.

Under normal conditions, a GPS can calculate your position accurately within about 15 meters (approx. 50 ft). Newer GPS receivers can take advantage of WAAS (Wide Area Augmentation System), a series of ground-based signals that improve GPS accuracy to within 3 to 5 meters (approx. 10 ft to 15 ft). Under good conditions, this can improve substantially. A GPS must have a direct line of site with the satellites above, meaning that tall buildings, steep hills/rock faces and dense vegetation can block the signal.
