Ground Based Augmentation System (GBAS) is a version of Differential Global Positioning System (DGPS) designed to reliably support airplane's all phase of approach, landing, departure and surface operations. Local ionospheric gradients are major threats to the GBAS, which prevents the advanced use of GBAS. A new monitor for detecting anomalous ionosphere to provide integrity assurance is implemented in this thesis. The monitor is based on the "Fast Initial Response" Cumulative Sum (FIR-CUSUM) quality-assurance method, which is sensitive to the small persistent shifts.
