Performance Airspace: WAAS
Topic Description
This topic discusses the Wide Area Augmentation System (WAAS,) which consists of equipment and software that improves the GPS Standard Positioning Service (SPS.) WAAS provides enhanced integrity, accuracy, availability, and continuity over and above a non-augmented GPS system. The differential correction function of WAAS provides improved accuracy required for precision approaches.
