Abstract:	The Federal Aviation Administration (FAA) has been pursuing the Wide Area Augmentation System (WAAS) as a precision landing system down to Category I minimums. The FAA Technical Center has established the Test Bed for the development and testing of augmentations to GPS. Previously, flight test results have hcen presented with three experimental Wide-area Reference Stations (WRSs) strategically placed at distances up to a 500 nautical mile (nmi) radius from the Technical Center. Through a recent joint effort with other FAA agencies, Stanford IJniversity, and industry, the test bed was expanded from three to eight experimental WRSs. Continuous coverage was provided by the eight stations over the contiguous US (CONUS). A cross-country flight test in December demonstrated near seamless operation from Atlantic City, NJ to Crows Landing, CA. Additionally, NASA Ames provided laser tracking during approaches using the experimental WAAS network. This flight test was the first of its kind to demonstrate a continuous WAAS data link coverage during a coast to coast flight. This paper will present an overview of the status of the test bed and discuss test results from this cross-country flight test.
