GPS Data/Memory Cards

GPS (global positioning system) is a navigational system involving satellites and computers that can determine the latitude and longitude of a receiver on Earth by computing the time difference for signals from different satellites to reach the receiver. Most GPS units require some sort of data or GPS memory card.
