Abstract :
In this paper, we propose an effective method to evaluate intermittent blocking on land-mobile satellite communications. This method uses the Global Positioning System. The results suggest that EFSAT, which provides higher elevation angles to areas in middle latitudes, is more suitable for land-mobile satellite communications in urban areas than a geostationary satellite in terms of blockage by features on the ground
