             abstract = "The ionosphere affects the propagation of global positioning 
                         system signals. Due to their special features, the equatorial and 
                         low-latitude ionosphere may produce particularly severe effects on 
                         them. The ground-based augmentation system has been developed to 
                         meet the safety requirements of civil aviation. To evaluate the 
                         performance of such a system, a statistical simulation model of 
                         the global positioning system signal-in-space has been developed, 
                         considering several components. The present work will focus on: 
                         (1) the ionospheric delay, with basis on statistical distributions 
                         of vertical total electron content obtained by the combination of 
                         the International Reference Ionosphere with data from the Rede 
                         Brasileira de Monitoramento Cont{\'{\i}}nuo, operated by 
                         Instituto Brasileiro de Geografia e Estat{\'{\i}}stica; (2) 
                         cycle ambiguity, characterized through the processing of the same 
                         data set; (3) ionospheric amplitude scintillation, simulated with 
                         basis on proper indices and the \α\μ probability 
                         distribution; and (4) ionospheric phase scintillation, generated 
                         according to its standard deviation. The statistical simulation 
                         model is based on a set of representative geophysical parameters 
                         and may be used to generate time series of pseudorange, carrier 
                         phase, and received signal power, to be applied as inputs to 
                         existing or future ground-based augmentation system testbeds. This 
                         provides an alternative to experimental data collection, which 
                         could be expensive and time-consuming. Additionally, such data may 
                         not be available for all regions and critical geophysical 
                         conditions of interest.",
