A short summary of this paper. Webthreats to GBAS. GBAS systems are limited by their inability to detect severe ionospheric gradients with the required missed-detection probability. A method for using GIVE values to insure the absence of these gradients is described here, and the use of UDRE to mitigate ephemeris and signal-deformation failures is also discussed.
