This paper reports the results of a flight test that successfully demonstrated the integration of a wideband-only Airport Pseudolite (WBAPL) into a prototype Local Area Augmentation System (LAAS). An analysis of the error performance exhibited by the prototype LAAS, with and without the inclusion of the WBAPL in the system, is presented. The inclusion of the WBAPL is shown to not only increase the availability of the system, but also improve the error performance. The improvement in performance is seen to be most pronounced when a reduced GPS SV set is available, a state that would otherwise result in the unavailability of LAAS. This is the first demonstration of simultaneous increase in availability and accuracy from the inclusion of a WBAPL into a prototype LAAS.
