Abstract
The objective of this research is to analyze the impact of rain attenuation on the quality of the Merah Putih satellite communication system on VSAT IP services at C-Band and Extended C-Band frequencies on the Bogor-Sorong communication link. The objective is to analyze the impact of precipitation intensity on rain attenuation by comparing two models, the Crane Global Model and the ITU-R P.618-14 Model. The aim is to identify the most suitable rain attenuation model based on the outcomes of the link budget. The result indicates that an increase in rain intensity and frequency results in a proportional rise in rain attenuation and vice versa. The ITU-R P.618-14 model is the most appropriate for this research, as it produces a more optimal link budget value. This is indicated by the C/N total parameter value for the C-Band frequency being 15.605415 dB and for the Extended C-Band frequency being 15.655086 dB. The Eb/No parameter value for the C-Band frequency is 10.58852 dB, while for the Extended C-Band frequency, it is 10.63819 dB. Moreover, the ITU-R P.618-14 Model yields a comparatively lower BER parameter value, which are 2.1849×10-6 for the C-Band frequency and 2.0742×10-6 for the Extended C-Band frequency.
