Internet via satélite: um estudo sobre a Starlink com simulação de constelações de satélites Walker Delta e Walker Star

Abstract

This work aims to study and understand the technologies employed in low satellite-based Internet access, focusing on the Walker Delta constellation used by Starlink. The research explores technical aspects of data transmission using satellites, including network topologies, self-steering antennas, signal modulations, and routing algorithms. Computational simulations were performed using Matlab software and the Aerospace toolbox, enabling the analysis of satellite communication scenarios and the comparison of constellations with different parameters, including packet routing between satellites. The results highlight the efficiency of the Walker Delta constellation in providing global coverage, positioning Starlink as a viable alternative to terrestrial fiber-optic networks, especially in remote areas. The study also includes a critical evaluation of the results obtained, comparing them with other works in the field, as well as discussing the limitations of the simulations conducted and proposing improvements for future research.
