Satellite Link Budget Calculator by Using Matlab/GUI

Abstract

In this paper, a satellite link budget calculator was done by using MATLAB -GUI program, the link budget is represented in one active screen, and it is designed to show the parameters that affects the RF signal when it is passing through the three main parts of the satellite communication system and regardless of the input signal power level. The results of the link budget program with the effects of changing the parameters will be shown inside the same active screen, which makes the users (students and trainers) analyze the reason that causes the weak signal when it reaches the satellite receiver.

A development of mobile application satellite link budget calculator – SATELEC

“…Desktop extensions, significant improvements to the object and graphics systems, support for parallel computing and GPUs, and the "Live Editor," which merges programs, descriptive text, output, and visuals into a single interactive, structured document [3]. MATLAB/GUI and a website were used to develop a few satellite link calculators [4,5]. However, no apps exist to assist students in comparing the calculated satellite link budget calculator for self-study.…”

“…There are numerous researches have been conducted on satellite link budget calculations. A satellite link budget calculator was done by Adil Hussein which focus on the link budget program's results and the impacts of modifying the settings are displayed on the same live screen, which forces users (students and instructors) to examine the reason for the weak signal reaching the satellite receive The calculator is developed MATLAB -GUI program [4]. Tajuddin N. et al developed a calculator/GUI using MATLAB in which the net power transmitted from the earth station is calculated taking into account the major factors that cause signal loss and attenuation along the path to the free space channel.…”
