Abstract
Earth stations elevation angle of antenna have to be established in order to communicate with satellites. In spite of crucial impairments in the uplink and down link of satellite communication between earth station and satellite such as noise, rain and atmospheric attenuations still earth station elevation angle is a key limiting factor to specify the communication link budget. In this paper, comparative study of satellite communication attenuation resulting from earth station elevation angle for geostationary and non-geostationary satellite system is presented. The present of free electrons in ionosphere is the impact factor to attenuate the radio wave when the high frequency radio waves penetrate it. Using MATLAB, the results report that the minimum elevation angle is about 5 ͦ but this makes negligible difference to the maximum value of transmission path when θ=0.
