How accurate is GPS?
Generally GPS error range is announced as 10m radius or over. Actual GPS data has wide spread distribution in a center point with recording GPS data change in fixed point. In normal environments, the error range is within 5m radius and the error range in wide open area such as golf club is in 1∼5m radius more accurate than city area. But in this case, actually sporadic error can be happened over 10m radius. GPS error correction in software programming means clearing of this kind of actual error or filtering of sporadic data change. Actually, the application of well-programmed filtering is very effective for clearing the GPS sporadic error and can provide more accurate coordination. But the principal weakness for application of filtering is a slow process for calculating the coordination. However, this kind of weakness is almost nothing for golfers because this time range is enough for considering golfer’s movement in golf club. Actual error range announced by famous GPS companies such
Today’s GPS receivers are extremely accurate, thanks to their parallel multi-channel design. Garmin’s 12 parallel channel receivers are quick to lock onto satellites when first turned on and they maintain strong locks, even in dense foliage or urban settings with tall buildings. Certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Garmin® GPS receivers are accurate to within 15 meters on average. Newer Garmin GPS receivers with WAAS (Wide Area Augmentation System) capability can improve accuracy to less than three meters on average. No additional equipment or fees are required to take advantage of WAAS. Users can also get better accuracy with Differential GPS (DGPS), which corrects GPS signals to within an average of three to five meters. The U.S. Coast Guard operates the most common DGPS correction service. This system consists of a network of towers that receive GPS signals and transmit a corrected signal by beacon transmitters.

A. Today’s GPS receivers are extremely accurate, thanks to their parallel multi-channel design. Certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Garmin GPS receivers are accurate to within 15 meters (49 feet) 95% of the time. Generally, users will see accuracy within 5 to 10 meters (16 to 33 feet) under normal conditions.
