Statistical distribution of GPS amplitude scintillations

► CCDF is suitable statistical apparatus for fitting GPS scintillation data. ► The distributions of GPS amplitude scintillations exhibit non-Gaussian behavior. ► The months of March and January had highest scintillation occurrences. ► The months of May-July showed the least probabilities of scintillation occurrences. ► Seasonally, March Equinox and December Solstice showed the highest occurrences.
