The WAAS difference

100 meters: Accuracy of the original GPS system, which was subject to accuracy degradation under the government imposed Selective Availability SA program. 15 meters: common GPS position accuracy without SA. 3 5 meters: common differential GPS DGPS position accuracy. Less than three meters: common WAAS position accuracy.

WAAS is a system of satellites and ground stations that supply GPS signal corrections, giving you better position accuracy. How much better? attempt an average of up to five times better. A WAAS capable receiver can give you a position accuracy of better than three meters 95 % of the time. And you do not have to buy extra receiving equipment or pay service fees to use WAAS.

How it Works
WAAS consists of roughly 25 ground reference stations located across the United States that monitor GPS satellite data. Two master stations, located on either coast, gather data from the reference stations and create a GPS correction message. This correction accounts for GPS satellite orbit and clock drift plus signal delays caused by the atmosphere and ionosphere. The corrected differential message is then broadcast through one of two geostationary satellites, or satellites with a fixed position over the equator. The info is matched with the basic GPS signal structure, which means any WAAS enabled GPS receiver can read the signal.

Who benefits from WAAS?
now, WAAS satellite coverage is only available in North America. there aren't ground reference stations in South America, so although GPS users there can get WAAS, the signal hasn't been corrected and could not improve the accuracy of their unit. For some users in the U.S., the position of the satellites over the equator makes it hard to get the signals when trees or mountains obstruct the view of the horizon. WAAS signal reception is ideal for open land and marine applications. WAAS gives expanded coverage both inland and offshore in comparison to the land based DGPS differential GPS system. another advantage of WAAS is that it doesn't require extra receiving equipment, while DGPS does.
