Ke. Crowe et Ra. Raines, A model to describe the distribution of transmission path elevation anglesto the iridium and Globalstar satellite systems, IEEE COMM L, 3(8), 1999, pp. 242-244
The quality of a satellite-based personal communications system (S-PCS) tra
nsmission path is heavily influenced by its elevation angle, The distributi
on of path elevation angles varies with a user's latitude but can be charac
terized by a single distribution with changing parameters. Through simulati
on, 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.
