WAAS capable receivers utilize an additional two geostationary WAAS satellites that are positioned over North America. The two additional WAAS satellites work in conjunction with several ground stations located throughout the USA. The WAAS ground stations work to interpret the existing GPS satellite constellation signals and make corrections to any errors that may exist. Errors from GPS satellites include satellite orbital errors, ionospheric disturbances, and timing. The WAAS ground stations make corrections to those errors and send them up to the two geostationary satellites.

Compared to the existing standard GPS signal, WAAS corrected GPS signals offer approximately 5 times greater position accuracy. Up until WAAS came along, GPS systems were capable of delivering non-precision approaches only. Using non precision approaches in less than desirable weather conditions could end in a missed approach due to low ceilings and lead to the flight terminating at an alternate airport.
