Abstract

The link communication between satellite and the Earth Station is exposed to a lot of impairments such as noise, rain and atmospheric attenuations.  The successful implementation of satellite communications need    to the efficient system design  to ensure  robust air links for the communications signals. However, the quality of  satellite signals are subject to degradation  through the atmosphere due to atmospheric impairments.  It is therefore crucial to design for all possible attenuation cenarios before the satellites  is deployed. The  performance indicator  "Link budget" is  a tabular method of calculating satellite communication system parameters. Link Budget  used to estimate  the effectiveness and reliability of  the link in satellite communication.  The link budget is the compilation of all gains and losses in the satellite communication link.   This paper presents the fundamentals of a satellite link budget  analysis of GEO satellite (Nile Sat ) to accounting of  atmospheric attenuation, signal strength and predict  the  quality of signal received at the ground station  during the atmospheric conditions in  Tripoli and Sebha  using  actual climatic parameters.  Evaluation of the satellite link performance also presents.  The performance of the satellite link  is evaluated  in terms of  carrier  to noise ratios, bit energy-to-noise ratios,  bit error rate and link margin.
