             abstract = "It is well known, today, that equatorial ionospheric 
                         scintillations affect performance of GPS receivers. Scintillation 
                         occurs when a radio wave crosses the ionosphere and suffers 
                         distortion in phase and amplitude. It also contributes to loss of 
                         lock of GPS receivers, resulting decrease of the number of 
                         available satellites and consequently yielding poor satellite 
                         geometry. Therefore, the required accuracy and positioning 
                         precision for aerial navigation are affected. Among other 
                         activities, EMBRACE, the space weather program of INPE, is 
                         monitoring and mapping the ionospheric scintillation over the 
                         South American equatorial and low latitude region in real time. 
                         This mapping is available in the internet by means of computer 
                         programs that retrieve data from a network of GPS receivers 
                         distributed in Brazil. These data are also being used to survey 
                         and predict the occurrence of ionospheric scintillation through 
                         data mining techniques.",
