GIS and Satellite Visibility: Viewsheds From Space
Overview The Global Positioning System (GPS) has recently become the significant mapping tool for millions of customers worldwide, providing its users with accurate terrestrial positions almost instantaneously. The functionality of a GPS receiver depends on the number of satellites to which it can establish an unobstructed line of sight. Current tools perform satellite visibility predictions without considering terrain or structures that block GPS signals, a major issue in mountainous and urban areas. This paper will describe a new tool for ArcGIS that predicts satellite visibility considering line of sight obstructions.
