2.5. Report from Electronic Navigation Research Institute (ENRI)(Susumu Saito, ENRI)=== Research activity ===ENRI is leading activities to characterize the spatial gradient in ionospheric TEC for aviation use ofGNSS in a framework of ICAO (International Civil Aviation Organization) Asia-Pacific region.
Ionospheric TEC gradient data from States/Administrations in the Asia-Pacific region are being
consolidated to develop a "threat model" for the ground-based augmentation system (GBAS) to enableprecise approach guidance for airplanes.
