| Abstract | ||
| This paper is devoted to study the footprint analysis of High Altitude Platform Cellular Communications, geostationary high altitude (GEO) and low earth orbit (LEO) satellites using three models: The first one is an approximated model for flat earth, which can be used in small coverage area or in case of high elevation angle and the correction of this model takes into consideration the curvature of the earth to correct the error of flat earth and gives good results for the minor and major axes of elliptical footprint. The second model of the spot beam depends on the inclination angle and gives good results compared to the HAP results of the first model. Also it gives good result for LEO satellite with elevation angle between 40 to 99 degrees. Also the second model was developed to give HAP good results for major and minor elliptical axes to calculate the beamwidth. The third model obtains the coverage area diameter with zero inclination angle and can be used for satellites at different LEO and GEO orbits and gives good results for a wide range altitude from 500 km to 36,000km, which is identical with practical results given by [12]. | ||
