Abstract:
Due to the widespread use of satellite communications including live TV broadcast, DVB-S and satellite Internet, it is necessary to accurately assess the level of signal received and the EIRP of the satellite. Nilesat21(7°W), Eutelsat3B(3°E), Badr(26°E), Express AM6(53°E) and Intelsat20(68.5°E) have been chosen to be meticulously assessed and analyzed.The chosen satellites contain the westernmost for Tehran to the easternmost, which has been listed above from west to east, respectively.In addition, the signal attenuation is closely monitored in the city of Tehran during rainfall for the above-mentioned satellites. In the meantime, the rain rate is also recorded.Another major factor that interferes with the reception of satellite signals is a phenomenon called The Sun Outage, a position in which the sun is exactly behind the satellite. We try to fully and comprehensively examine and assess that in this project
