Two Years Characterization of Concurrent Ku-band Rain Attenuation and Tropospheric Scintillation in Bandung, Indonesia using JCSAT3

In this paper, we present two years statistics on concurrent rain attenuation and tropospheric scintillation in Bandung (6.9degS, 107.6degE), Indonesia using 12.247 GHz horizontally polarized CW beacon signals of JCSAT3 (Pos=128degE, Az=73.2deg, El=64.7deg) satellite. From the experiment results, we have found out that on a rainfall rate R 0.01 120 mm/h, the rain attenuation A 0.01 measured was around 17 dB . Concerning to the tropospheric scintillation, we have noted that in a tropical region such as Indonesia, the magnitude of the Ku-band scintillation is seasonal dependence, reaching variance 0.4 dB (maximum) in rainy season and 0.2 dB (minimum) in dry season
