Long term attenuation statistics at 11.6 GHz in the three Italian Main Stations
Abstract
Results are presented from the 5-year attenuation-measurement campaign conducted with the SIRIO satellite at 11.6 and 17.8, which used near-continuous measurements at the lower frequency from the Italian ground stations at Fucino, Lario, and Spino d'Adda, and fewer measurements at the higher frequency from Fucino and Lario. The long-term statistics thus obtained have been applied in the design of the Italian domestic satellite system Italsat, which is to begin operating in 1989. Attention is presently given to annual worst month, time-of-day dependence, rain rate attenuation correlation, and frequency scaling statistics.
