Abstract
The rain attenuation exceedance and the corresponding link availability have been calculated for any location in Canada for a Satcom link in the 10-45 GHz range with arbitrary values of the link parameters. Contours, with arbitrary constant values, of these two parameters are also determined for any region in Canada. The effect of site diversity on these results can be studied. The results are presented in different formats to facilitate their use in a system design. The CCIR rain attenuation prediction model, Hodge site diversity model and long term rain statistics have been used for this work. Following a brief review of the subject, representative rain attenuation exceedance and link availability results are given for a Satcom link at 20, 30 and 44 GHz for a few selected values of the link parameters. From the point of view of rain attenuation, this study indicates the feasibility of a 20-44 GHz Satcom system for Canada with approximates to 99.5% link availability.
