Abstract :
This paper reports results of the 20 GHz orbital diversity experiment between the geostationary satellites Olympus (19°W) and Italsat (13°E), as viewed from Spino d´Adda, Po Valley, northern Italy. The results show that: (a) the statistical gain is significant; and (b) for a small angular separation in the geostationary orbit between the satellites (32° in our experiment) the gain, normalized to single link attenuation and expressed in percent, is, as a rule of thumb, of the order of magnitude of this angle expressed in degrees, 30% in our experiment
