7 2 RIBAS MACHADO, Ederson
The objective of this work is develop a comprehensive tool in LabVIEW that will offer to the students the ability to test different satellite links, and derive the end-to-end system performance. This software will be able to, from a set of input parameters, creatively show the expected link budget of the satellite  in terms of determinate parameters like EIRP, G/T, BER.
