Rain Rate and Rain Attenuation Prediction For Satellite Communication in Ku Band Beacon Over TURKSAT Golbası

Satellite beacon is a signal which does not modulated and sent to ground in constant frequency with a specific designed power. Beacon signals are used by ground station antenna users track the satellite easily. The satellite operators generally choose beacon signal at Ku Band frequency band since this band is more resistant to rain attenuation. Ku band satellite system performance describe by the contribute of rainfall rate and rain attenuation. This paper includes the comparison of rain attenuation in Ku band beacon and taking as a reference ITU – 838 model caused by rain fall rate in TURKSAT premises. It is compared by calculating that how signals affected from rain between 2012, and 2019 observations for a TURKSAT satellite and in this measurement both theoretical formula and data are used.
