WebWAAS hardware consists of: 38 ground reference stations, 3 master stations, 3 geostationary satellites with navigation transponders onboard, 6 uplink stations, 2 operational control centers, and the WAAS terrestrial communications network. Previous article Question: How Lon To Get Icing Aviation? WebWAAS stands for Wide Area Augmentation System. Even though the FAA created it, many GPS receivers now use it to formulate more accurate positions. WAAS uses a separate network of ground stations and satellites to calculate any errors in the existing GPS network and help your receiver correct them.
