The communication between the global navigation satellites and ground observation stations is provided by the electromagnetic waves that emits from the satellites. When the satellite signals pass through the Ionosphere, they are refracted by the different Ionospheric layers. The precise determination of the Ionospheric refractivity index is crucial for the evaluation of the Ionospheric delay that depends on the refraction ratio.
