SBAS is based on differential GPS, but applies to wide area (WAAS/EGNOS/MSAS) networks of reference stations. Corrections and additional information are broadcast using geostationary satellites. The signal strength of a satellite is a measure of the information content of the signal, relative to the signal's noise. [. . . ]
