AbstractIn LEO Satellite System, users usually need to obtain their position, maximum elevation angle, and visibility time period. These three parameters have a great influence on the assessment of signal quality. The degree of influence depends on the distribution of transmission line path elevation angle and the height of location. The combination of elevation angle distribution and satellite altitude can be used to provide the distribution of path losses. The elevation angle of transmission path is an important parameter in the assessment of link quality. Signal impairments from multi-path interference, shadowing and blocking tend to be more severe at low elevation angles. This research study presents a method to find out the distribution of transmission path elevation angles for any location in the world. In this research study the distribution of transmission path elevation angles will be calculated and from these angles the maximum elevation angle will be obtain for each location. On the basis of these resultant maximum elevation angles performance of selected LEO satellite systems will be compared.
