Abstract:	The purpose of this study was to experimentally evaluate the effects of GNSS antenna pattern, antenna height, and site environment on GBAS ground station accuracy and availability. A number of antenna types were installed in a GBAS ground station. Several weeks of GBAS Type 1 Message data were collected. Accuracy was computed and compared to GAD B and C curves, error distribution tails were compared to Gaussian distributions, and VPLH0 and VPLH1 were plotted. The effects of ground-planes and choke-rings were also measured. Two different sites were evaluated.
