Effects of 23rd Solar Cycle on TEC Measurement over Bahrain – A Case Study

Global Positioning System (GPS) is a worldwide radio-navigation system through which the position of an object on Earth and in its vicinity can be precisely calculated. However, errors in the satellites signal propagation affect the positioning calculation done by ground receivers. The Ionosphere is the most significant source of that error, with errors scaling up to tens of meters. To eliminate Ionospheric errors, the number of total electron content (TEC) in the Ionosphere must be calculated. In this study, a comparison has been performed between the peaks of the seasonal graphs obtained by daily calculations of vertical total electron content of two collocated receivers (BAHR & BHR1 / BHR1 & BHR2) and the daily total sunspot number (DTSN). We found there to be a direct correlation between the two.
