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.",
