Wide Area Augmentation System - A GPS-based navigation and landing system that provides precision guidance to aircraft.
Wide Area Argmentation System
A satellite navigation system designed by the U.S. Federal Aviation Administration (FAA) to boost the accuracy of GPS satellite navigation. Improvements in accuracy are approximated to be within 7 meters. Note: Currently, WAAS is not fully implemented. It was created for aviation applications. It uses geostationary satellites over the equator, which makes WAAS signals easily blocked in North America by terrain obstructions. Users may experience temporary loss of WAAS support, especially in wooded areas.
An augmentation to GNSS that uses geostationary satellites to broadcast GNSS integrity and correction data, and additional ranging signals.
Wide Area Augmentation System (WAAS) is a differential correction source for GPS. The FAA built the system for aviation navigation. The signal is satellite-based and only available in the United States. The signal is free and can be used with any WAAS-enabled GPS receivers. No special GPS antenna required.
The ide rea ugmentation ystem is the American SBAS system developed by the FAA.WAAS is designed to improve the accuracy and ensure the integrity of information coming from GPS satellites. The FAA is moving directly to a Lateral Navigation/Vertical Navigation (LNAV/VNAV) capability using WAAS with expected capability in 2003.

Wide Area Augmentation System. A system of satellites and ground stations that provide GPS signal corrections for better position accuracy. A WAAS-capable receiver can give you a position accuracy of better than three meters, 95 percent of the time. (At this time, the system is still in the development stage and is not fully operational.) WAAS consists of approximately 25 ground reference stations positioned across the United States that monitor GPS satellite data. Two master stations, located on either coast, collect data from the reference stations and create a GPS correction message. For more information, see What is WAAS?, or visit the FAA's website.
ide rea ugmentation ystem The US FAA system developed to provide extremely accurate GPS signals for aircraft navigation. Coverage extends from Hawaii to Puerto Rico, Mexico to well north in Canada and about 100+ miles out to sea around most of the continent. (See Satellite DGPS)

A WAAS-capable receiver can give you a position accuracy of better than three meters, 95 percent of the time. WAAS consists of approximately 25 ground reference stations positioned across the United States that monitor GPS satellite data. Two master stations, located on either coast, collect 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 information is compatible with the basic GPS signal structure, which means any WAAS-enabled GPS receiver can read the signal.
An enhancement to the GPS system providing greater navigation accuracy and system integrity and permitting GPS to be used for precision instrument approaches to most airports.
WAAS stands for Wide Area Augmentation System, but that doesn't really describe what it is. Garmin has an excellent description on WAAS .

Wide area augmentation system. A series of differential GPS ground stations that broadcast correction information to airborne GPS receivers, allowing them to achieve a more accurate position determination.
Wide Area Augmentation System (in USA)
Wide Area Augmentation System. This system is a series of satellites and ground antennas that correct data transmitted between Satellite and GPS devices. This system allows for routes to be more accurate, within a range of roughly three meters. This system hits the three meter accuracy range 95% of the time.

Wide Area Augmentation System. A U.S. Federal Aviation Authority (FAA) system of equipment and software that supplements GPS accuracy, availability and integrity. The WAAS provides a satellite signal for WAAS users to support enroute and precision approach aircraft navigation.
System of satellites and ground stations that provide GPS corrections. Increases position accuracy to within 3 meters approximately 95 percent of the time. The system comprises of 25 ground towers across the United States that monitor GPS signals. Master stations located on each coast create GPS corrections from data collected from the ground towers. Currently this system is still under development and is not available in all locations.
Wide Area Augmentation System. This is something that a lot of GPS receivers now have. It's a clever invention which shows your position on the map with much greater accuracy. You'll be able to see yourself on a map with 3 meters accuracy on a handheld using WAAS.
Wide Area Augmentation System, a system to improve accuracy of GPS significantly. The system is not yet fully operational but will be in the next few years. It does not yet appear to be working in Europe though. WAAS is a satellite signal improvement.
