Satellite Navigation - WAAS - How It Works | Federal Aviation ...

WAAS system overview The Wide Area Augmentation System (WAAS) is an air navigation aid developed by the Federal Aviation Administration to augment the Global Positioning System (GPS), with the goal of improving its accuracy, integrity, and availability. Essentially, WAAS is intended to enable aircraft to rely on GPS for all phases of flight, including approaches with vertical guidance to any ...

Do you understand how WAAS works, and how it helps you fly highly-accurate GPS approaches? Wide Area Augmentation System (WAAS), Defined According the FAA's Instrument Flying Handbook, "WAAS is designed to improve the accuracy, integrity, and availability of GPS signals." WAAS service is available for all classes of aircraft in all phases of flight, including: en route navigation, airport ...

Wide Area Augmentation System Satellite navigation accuracy can be enhanced through systems designed to improve position precision and reliability. Understanding the Wide Area Augmentation System (WAAS) helps pilots see how corrected GPS signals support more accurate navigation and enable advanced instrument approach capabilities.

Description The Wide Area Augmentation System (WAAS) provides extremely accurate navigation capability by augmenting the Global Positioning System (GPS). It was developed for civil aviation by the Federal Aviation Administration (FAA) and covers most of the U.S. National Airspace System (NAS) as well as parts of Canada and Mexico. WAAS provides service for all classes of aircraft in all phases ...
