What is WAAS?
WAAS, available in North America is a provider in the worldwide SBAS (Satellite Based
Augmentation System) navigation system. CBAS provides GPS signal corrections to SBAS
users, for even better position accuracy, typically better than three meters. There are three more
SBAS providers, MSAS (Multi-Functional Satellite Augmentation System) for Japan, EGNOS
(Euro Geostationary Navigation Overlay Service) for Europe and GAGAN (GPS And GEO
Augmented Navigation) for India. The illustration below shows the coverage area. (Accuracy
may be affected when using a GEO satellite not within your current location.) This manual uses
“WAAS” for these three providers generically.
