WAAS 101
One of the more popular acronyms in our industry today is WAAS - Wide Area Augmentation System. This term relates to a space-based (GPS) augmentation system aid that has been developed to augment the accuracy of GPS in an aircraft and much more.

WAAS improves accuracy, integrity, and availability of the GPS signals. It provides correctedGPS signal data that reduces errors which may be caused by temperature, baro mis-set effects, ionospheric conditions, solar activity or atmospheric conditions.
