GPS is the most widely used global positioning technology. Originally developed by the US Department of Defense, GPS is used for many different applications including, offshore ocean navigation, direction finding, exploration and vehicle locating. Without Selective Availability, GPS is accurate to within a radius of 6.3 meters of a location (95% of the GPS points fall within this radius).
