Abstract

Earth’ s upper atmosphere, called the ionosphere, is a highly variable region with complex physical characteristics in which the density of free electrons are large enough to have considerable effects on signals’ propagation travelling through this dispersive medium. As GPS signals travel through the ionosphere, they may experience rapid amplitude fluctuations or unexpected phase changes. This is referred to as ionospheric scintillation. ionospheric scintillation which caused by small scale irregularities in the electron density, is one of the dominant propagation disturbances in radio frequency signals. These irregularities severely affect the accuracy and reliability of GPS measurements. Therefore, it is necessary to investigate ionospheric scintillation and its effects on GPS observations. Hence, the focus of this paper is to detect ionospheric scintillations over Iran’ s region and to investigate these effects on GPS observations in more details. The results will show the occurrance of this phenomenon and its effects on GPS observations.
