- Abstract
- Satellite communications system operating in frequency band over 10GHz, is restricted in steady operation due to severe signal attenuation by dispersion and absorption of the air including rainfall. Since signal attenuation by rainfall in the satellite system is more serious than that of the terrestrial system, it should be exactly expected from the system design phase. There are many rain attenuation prediction models for satellite links like ITU-R model. If the overseas model is applied to the design and operation of the domestic satellite system, it can occurs big error compared with real attenuation quantity in domestic environment. To estimate it more exactly, we are developing appropriate effective path length for domestic environment for prediction model.
