Ionospheric Irregularities Predictions and Plumes Characterization for Satellite Data Validation and Calibration
Abstract
During the above period the following activities were developed: 1) The ionospheric plumes were characterized for 3 longitudinal sectors (east of Brazil, Peruvian coast and pacific zone)using VHF radars and algorithms were developed to represent the plumes in function of solar flux. 2) The GPS signal during ionospheric irregularities was analyzed and the effect of the decorrelation was established, the variability of amplitude scintillation pattern was studied and a model alpha-Mi for the scintillation amplitude distribution was generated and its results were compared with the Nakagami-m and Rice models. 3) The performance of 6 GPS receivers under scintillation environment was studied. 4) An ionospheric prediction model was developed in collaboration with Dr. Emanoel Costa from PUC/Rio de Janeiro. Data from one VHF radar and from GPS receiver was used. 5) The correlation of the equatorial S4 scintillation index and S4 under EIA was analyzed.
