Abstract: This paper presents a new method for generating obstruction diagrams as a function of site obstacles for GPS observations. The proposed method takes advantage of the human ability for stereoscopic vision. Instead of going on the site and measuring the azimuth and elevation angle of every obstacle in the vicinity of a prospective GPS point, the photogrammetric approach proposes using a visibility cone injected into a stereoscopic model. In this way, the time consuming and costly phase of site reconnaissance is eliminated. In the presence of obstructions, the cone rays that are lower than the obstacles are raised like floating lines. Afterwards, by recording the azimuth and elevation angles of these rays, obstruction contours can be generated. With this diagram, superimposed on the satellite track plot, the mission planner can evaluate the best (;PS observation window based, for example, on Geometric Dilution of Precision (GDOP). A practical test shows the applicability and feasibility of the method.
