WAAS stands for which of the following?

Explanation:
WAAS is a satellite-based augmentation system that enhances GPS for aviation. It provides corrections for satellite timing and ephemeris data, plus integrity monitoring, by using a network of ground reference stations across the United States, a master station, and geostationary satellites that broadcast the corrections to receivers. This improves positional accuracy to within a few meters and adds vertical guidance for approaches (LPV), increasing IFR reliability. The term stands for Wide Area Augmentation System. The other phrases don’t describe an official aviation navigation augmentation program.
