In this study selected Koreasat 3, which uses the Ku-band(14㎓/12㎓) frequency, and analyzed the beacon signal level data according to the rain rate from June to August in 2001. Then to provide analysis, the experimental data was compared with that obtained using typical rain attenuation models, such as the ITU-R model, the SAM model and the Global model, which have previously been used in satellite communication systems. Also, this study analyzed predicted area path diversity gain on the basis of the path of Daejeon-Koreasat 3 in order to compensate excess attenuation caused by rain, and estimated link budget by hour rate on the basis of the ITU-R model. Establishing the reliability of path diversity gain and link budget achieved by this study may be greatly used as a basic material to design satellite communication system in the future. Furthermore, according to methods to be applied, it could be utilized to construct microwave communication network or broadcasting network on the ground.
