The European Space Agency (ESA) in cooperation with Inmarsat launched the Alphasat communication satellite in 2013 with an experimental payload developed under the frame of ARTES 8 telecommunications program. The Aldo Paraboni payload is hosting two coherent beacons to carry out scientific measurements in the Ka and Q band. Wave propagation characterization and rain attenuation measurements are done in order to qualify the radio channel and improve the existing propagation models. In this paper
more » ... we detail our measurements and compare them with ITU-R recommendations for rain attenuation statistics. To compare the measured rain attenuation with ITU models it is essential the appropriate selecting the rain events in the time series. In this paper, we present the results of measurements and also manually selected rain events where the goodness of selection is qualified by ITU-R P.837 rain probability for a specific geographical location.
