“…Various statistical models exist for the prediction of the Complementary Cumulative Distribution Function (CCDF) of scintillation intensity (dB) and variance (dB 2 ), using temperature and/or humidity at ground level [1][2][3][4][5][6], profiles [7] or information about clouds [8]. Various measurements have been performed during Olympus and Italsat campaigns in Europe and as well as during other propagation campaigns in tropical climate [9] [10].…”

The purpose of this paper is to present the use of Numerical Weather Prediction software to generate 4Dmeteorological parameters for the characterization and simulation of tropospheric scintillation for geostationary and nongeostationary Earth-satellite links. A preliminary test has been performed against measurements at 30 degree elevation for a geostationary satellite link and an analysis of the turbulence characteristics on a low elevation Earth-space link has been proposed.

“…However, distinguishing actual scintillation from rapid variations of rain attenuation in the presence of rain is not straightforward to Marzano and d'Auria (1998). In addition, it is of less interest to investigate scintillation under rainy conditions for low-availability satellite system design purposes because rain attenuation is usually much more pronounce than scintillation fades (Marzano et al 1999;Ortgies 1993;Otung 1996;Otung and Savvaris 2006). For those reasons, only clear-weather scintillation is accounted for in this project (impairments such as rain attenuation and noise are eliminated).…”

“…The Karasawa model (Karasawa et al 1988b), for example, was developed in Yamaguchi (Japan). Other models, such as the Otung model (Otung 1996) and the Van de Kamp model (Van De Kamp et al 1999) were developed using a European database. Because a large variation exists between the climate in Europe and Indonesia, an analysis of the tropospheric scintillation prediction models against the measured scintillation intensity for Indonesia (tropical climate) is needed.…”

Tropospheric scintillation is a phenomenon that will cause signal degradation in satellite communication with low fade margin. Few studies of scintillation have been conducted in tropical regions. To analyze tropospheric scintillation, we obtain data from a satellite link installed at Bandung, Indonesia, at an elevation angle of 64.7°and a frequency of 12.247 GHz from 1999 to 2000. The data are processed and compared with the predictions of several well-known scintillation prediction models. From the analysis, we found that the ITU-R model gives the lowest error rate when predicting the scintillation intensity for fade at 4.68%. However, the model should be further tested using data from higher-frequency bands, such as the K and Ka bands, to verify the accuracy of the model.

“…However, because a carrier frequency becomes higher according to the increase in the required channel capacity of satellite communication links in the next generation, the analysis of the effects of atmospheric turbulence should be done for applications at the higher carrier frequencies such as Ka-band, a millimeter wave and an optical wave. Some studies are conducted for satellite communications in such frequencies (Marzano et al, 1999;Matricciani et al, 1997;Matricciani & Riva, 2008;Mayer et al, 1997;Otung, 1996;Otung & Savvaris, 2003;Peeters et al, 1997). We study the effects of atmospheric turbulence on satellite communications in such high frequencies by the theoretical analysis of the moments of wave fields given on the basis of a multiple scattering method (Tateiba, 1974;1982).…”
