Abstract

A new and simple method to calculate the time variation of the elevation angle for LEO satellites is presented in this article. The method is useful to predict the link availability of LEO satellites due to propagation impairments. The method has been applied as a realistic study of LEO satellite flying over different regions of the Kingdom of Saudi Arabia (KSA). It is found that the percentage of time during which this satellite is visible (P%) over KSA decreases with the increase of the elevation angle (0). The variation of P% with could be modelled either by an exponential function, or simply by a decreasing power's law relation
