Abstract
We propose a fast technique to simulate the effect of ionospheric
scintillation on GNSS signals. The method uses a single-layer
phase screen model of the ionosphere with the Huygens-Fresnel integral being determined analytically. The adopted model of the ionosphere assumes an infinite train of plasma bubbles drifting
eastward with constant velocity. By modifying the total electron content of the plasma bubbles
different values of the scintillation index 𝑆4 can be obtained. This model is useful
for the simulation of equatorial scintillation scenarios.
