One-minute tropospheric scintillation data recorded in Philippines over 3 years have been collected for analysis using a Superbird C Satellite (144°E) at 12.2 GHz with an antenna elevation angle of 58.8°. The results obtained from the analysis of seasonal variations and different tropospheric scintillation models proposed by various authors have been presented in this paper. Considerable differences...
Tropospheric scintillation is the rapid fluctuation and degradation of satellite signals due to changes in refractive index of atmosphere. This phenomenon tends to affect signals more strongly at frequencies above 10 GHz. This paper introduces a new scintillation prediction model created by modifying the existing Karasawa model. The proposed model is compared with currently existing model using scintillation...
