ResumoConsidering the unique geometry of the geomagnetic fields near the magnetic equator and low-latitude regions, the satellite communication systems such as GNSS (Global Navigation Satellite System) and other related radio systems in the Brazilian sector are strongly affected by the effects of the solar and geomagnetic activities. The first-order delay caused by the ionosphere is proportional to the Total Electron Content (TEC) along the signal path between the satellite and the receiver. As a result, precise modeling of the ionospheric TEC is very important and remains a challenge for positioning and navigation systems such as GNSS. Hence, this study investigates the performance of the NeQuick 2 model for the prediction of TEC variation during high and moderate solar activities. GPS data from a station located at the magnetic equator has been ingested in the NeQuick model for ionospheric correction over this region. The results of the diurnal and seasonal variations have been presented considering both equinoxes and solstices. The diurnal variation in both observation and model presents the day-to-night variation with higher values of VTEC during the day and lower values at night. Seasonal variation showed a peak in equinox and a minimum in the solstice. The comparison between the GPS-TEC and NeQuick 2 model revealed a great improvement in the model after data ingestion.
