WAAS stands for

• A. Wireless Area Augmentation System
• B. Wide Area Augmentation System
• C. World Area Augmentation System
• D. Weather and Airspace System

Answer: (B)

WAAS stands for Wide Area Augmentation System. It’s a satellite-based enhancement for GPS used in aviation to improve the accuracy, integrity, and availability of GPS signals across a wide region. The system relies on a network of ground reference stations to monitor GPS errors, a master control station to compute corrections, and geostationary satellites to broadcast those corrections to aircraft. With WAAS-enabled receivers, pilots can access more precise positions and, in many cases, precision approaches such as LPV. The other phrases don’t describe this FAA-developed aviation augmentation system, so they’re not correct.
