Most global navigation satellite systems (GNSS) are subjected to errors induced by the ionosphere. Because ionospheric delay affects the speed of microwave signals differently depending on their frequency—a characteristic known as dispersion, delays measured on two or more frequency bands can be used to measure dispersion, and this measurement can then be used to estimate the … WebThe WAAS ionospheric threat model seeks to characterize deviations from planarity in worst case situations in which a chi-square detector has not yet reached a 99.9% …
