ABSTRACT
The site diversity is used to mitigate the rain attenuation onsatellite links. The attenuation is estimated through the rainrate-rain attenuation conversion based on the Assis-Einloft physicalmodel in this study. Through the comparison of instantaneousattenuations at two receiving sites the site diversity gain isestimated. Examples of rain rate measurements in the Czech Republicfollowed by the site diversity gain estimation are added. This gain isgreater on west-east situation of receiving sites achieving 10 dB on0.01% exceedance level/100 km.
