In this paper, we apply the ITU-R P.618-8 model with data from the ITU-R P.837-7, Tropical Rain Measuring Mission (TRMM) and Global Precipitation Mission (GPM) satellite to determine the level of attenuation and available link margin for a LEO system such as Telesat. The specific and predicted attenuation for chosen six candidate ground stations (Abuja, Hartbeesthoek, Cairo, Longonot, Port Louis and Praia) is computed and results presented for 0.001%-1% unavailability time in a year. Setting a link margin of 0.36dB, the available link margin and the best candidate ground station for a LEO system such as Telesat is determined. The approach used can be implemented for other potential ground stations and LEO communication systems over Africa.
