Abstract :
The design of satellite communication system is a complex process requiring compromises between many factors to achieve the best performance at an acceptable cost. In the present world GEO satellites carry the vast majority of the world´s satellite traffic, therefore it becomes utmost for the link designer to design with a optimum utilization of space segment as well as transponder downlink EIRP. We (authors) has performed the experiments by varying some of the entities which play a vital role in the link budget and observed the complete physical changes affecting the overall link budget profile. Using such results based upon our work, we performed a theoretical predictions on some of the major problems experienced by the satellite users which includes losses, and attenuation by rain or by equipments, outage of the system etc. Results of these theoretical predictions, acted as an impetus in knowing that the mismanagement of the link budget calculation lead to vital problems such as interference, cross polarization of the antenna and rising of the noise floor of transponder etc.
