             abstract = "Ionospheric scintillation is a phenomenon that occurs after 
                         sunset, especially in the low-latitude region, affecting radio 
                         signals that propagate through the ionosphere. Depending on 
                         geophysical conditions, ionospheric scintillation may cause 
                         availability and precision problems to Global Navigation Satellite 
                         System users. The present work is concerned with the development 
                         of an extended model for describing the effects of the amplitude 
                         ionospheric scintillation on GPS receivers. Using the - 
                         probabilistic model, introduced by previous authors in different 
                         contexts, the variance of GPS receiver tracking loop error may be 
                         estimated more realistically. The proposed model is developed with 
                         basis on the - parameters and also considering correlation between 
                         amplitude and phase scintillation. Its results are interpreted to 
                         explain how a receiver may experience different error values under 
                         the influence of ionospheric conditions leading to a fixed 
                         scintillation level S4. The model is applied to a large 
                         experimental data set obtained at SAo Jose dos Campos, Brazil, 
                         near the peak of the equatorial anomaly during high solar flux 
                         conditions, between December 2001 and January 2002. The results 
                         from the proposed model show that depending on the - pair, 
                         moderate scintillation (0.5S40.7) may be an issue for the receiver 
                         performance. When S4>0.7, the results indicate that the effects of 
                         scintillation are serious, leading to a reduction in the receiver 
                         availability for providing positioning solutions in approximately 
                         50\% of the cases.",
