"A Model for the Prediction of the Advantage of Triple Site Diversity Applied to Earth-Space-Paths"

In heavy rain climatic regionss attenuation caused by rain presents a great problem for satellite communications at frequencies above 10 GHz. In some severe casess double site diversity protection can be proved to be inadequate and consequently triple diversity becomes indispensable. In this papers a theoretical model is presented for estimating the improvement in rain outage performance caused by triple site protection. Experimental results taken from some parts of the United States such as New Jerseys and Florida are compared with the theoretical values and the agreement has been found to be encouraging.
