The use of higher frequencies for satellite multimedia communication systems calls for research of the atmospheric propagation effects at these bands (rain, cloud and gaseous attenuation, scintillation, and depolarization). Alphasat was successfully launched on 25 July 2013. This largest and most powerful European telecommunication satellite carries, besides a commercial payload belonging to the mobile...
In order to study propagation effects for future satellite communication frequencies, the Alphasat Aldo Paraboni payload includes two beacon transmitters at Ka-band (19.701 GHz) and Q-band (39.402 GHz). Among all atmospheric effects, rain has the biggest impact on signal transmission. Often a single statistical relationship (derived from climatic parameters) between rain rate and specific attenuation...
