摘要：

The quality of a satellite-based personal communications system (S-PCS) transmission path is heavily influenced by its elevation angle, The distribution of path elevation angles varies with a user's latitude but can be characterized by a single distribution with changing parameters. Through simulation, model fitting and regression analysis, a set of equations is presented which allows the distribution of elevation angles to both Globalstar(1) and Iridium(2) systems to be determined for any point on the earth between +/-60 degrees latitude.
