WAAS
Wide Area Augmentation System. WAAS was established by the Federal Aviation
Administration (FAA) for flight and approach navigation for civil aviation. WAAS
improves the accuracy and availability of the basic GNSS signals over its coverage
area, which includes the continental United States and outlying parts of Canada and
Mexico.

The WAAS system provides correction data for visible satellites. Corrections are
computed from ground station observations and then uploaded to two
geostationary satellites. This data is then broadcast on the L1 frequency, and is
tracked using a channel on the GNSS receiver, exactly like a GNSS satellite.

Use WAAS when other correction sources are unavailable, to obtain greater
accuracy than autonomous positions. For more information on WAAS, refer to the
