The Wide Area Augmentation System (WAAS) is an air navigation aid developed by the Federal Aviation Administration to augment the Global Positioning System (GPS), with the goal of improving its accuracy, integrity, and availability. Essentially, WAAS is intended to enable aircraft to rely on GPS for all phases of flight, including approaches ...
Satellite-based augmentation systems (SBAS) support wide-area or regional augmentation through the use of additional satellite-broadcast messages. Using measurements from the ground stations, correction messages are created and sent to one or more satellites for broadcast to end users as differential signal.
Similar service is provided in North America by the Wide Area Augmentation System (WAAS), in Russia by the System for Differential Corrections and Monitoring (SDCM), and in Asia, by Japan's Multi-functional Satellite Augmentation System (MSAS) and India's GPS-aided GEO augmented navigation (GAGAN).
GNSS augmentation is a method of improving a navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process, for example, the Wide Area Augmentation System, the European Geostationary Navigation Overlay Service, the Multi-functional Satellite ...
The system is known in the US as WAAS (Wide Area Augmentation System), in Europe as EGNOS (European Geostationary Navigation Overlay System), in Japan as MSAS (MTSAT Satellite Based Augmentation System) and in India as GAGAN (GPS-aided geo-augmented navigation). The system employs various techniques to correct equatorial anomalies.
Each reference station in the Wide Area Augmentation System includes three GPS antennas. The coordinates of each antenna, along with its elevation, are listed below. The coordinates of each antenna, along with its elevation, are listed below.

Wide Area GPS Enhancement (WAGE) is a method to increase the horizontal accuracy of the GPS encrypted P(Y) Code by adding additional range correction data to the satellite broadcast navigation message. Per a 1997 article, [citation needed] the navigation message for each satellite is updated once daily or as needed. This daily update of each ...
