One of the most popular products today is a GPS (Global Positioning System) which is a satellite-based navigation system made of a network of 24 satellites placed into orbit by the U.S. Department of Defense. There are no subscription fees or setup charges to use GPS. Many people wonder how accurate GPS receivers are today. Today’s GPS receivers are extremely accurate, thanks to their multi-channel design. One of the most popular GPS, Garmin, uses 12 parallel channel receivers and is accurate to within 15 meters on average. More improved version of GPS with WAAS (Wide Area Augmentation System) can improve accuracy to less than three meters on average. Alternative way of improving the accuracy is to go with DGPS (Differential GPS), which corrects GPS signals to three to five meters.
