Ionospheric plasma bubble and total electron content monitoring and mapping over the Brazilian territory to researches and applications


The ionosphere, due to the presence of electrons and ions, causes delay in the electromagentic signals crossing it. At tropical latitudes, besides such delay, the existence of the ionospheric plasma irregularities causes scintillation in the GPS signals that can affect the GPS navigation and positioning or even can interrupt such services. This delay in the signal is quantified by the total elctron content (TEC). The TEC as well as the scintillations are parameters that can be measured by GPS receivers. In Brasil we have an array of many GPS receivers to determine the TEC and about 14 scintillation monitors and many more will be installed in 2007. These data need to be storaged and leave availablein the WEB in real time. Computational tools like data mining and neural arrays are going to be used to try to correlate the measured parameters and the irregularity occurrence, ie, to try to predict the irregularities. Based on this data base many development of codes and scientific research activities are going to be developed. (AU)
