Ensuring WAAS Performance and Effectiveness for Application in the National Airspace System (NAS)

Peter Brodie, Gene Cangiani, Robert Sung

Abstract:	The FAA’s WAAS, or Wide Area Augmentation System is a GPS based safety critical system consisting of a ground network of integrity monitoring and reference stations and space based transponders, intended to replace the current system of airport and airway located navigation aids. This paper presents a means of making the WAAS signals more robust, more secure, and more accurate, thereby enhancing flight safety of this innovative planned navigation asset. Achieving a 30 dB increase in anti jam/spoofing or interference resistance is possible along with improved ranging accuracy and a ten fold increase in signal bandwidth. This approach by design, will supply improved control of time synchronization, short term stability, and code to carrier coherence.
