Abstract
The introduction of Differential GPS (DGPS) into application improves the position accuracy, which leads to the possibility for the use of GPS into precise approach. However, the accuracy and integrity of DGPS are limited due to the influence of ionosphere error including both the spatial and temporary gradient. They also bring in some extra error due to the effect of ionosphere temporal and spatial gradient based on the analysis of this error, a new algorithm is formulated to design optimal Hatch filter whose smoothing window width varies flexibly with the satellite elevation, ionosphere variation and distance from the user to the reference station. Through the application of the method to GBAS and the comparison to the performance of traditional Hatch filter based GBAS, it reveals that the improved GBAS is more robust for the challenge of ionosphere storm.
