In this work, we describe a generalized method based on clustering analysis for a clustering stage of the Gaia XM, including additional parameters such as magnitude and proper motion. The performance of the implemented algorithm is assessed through real-case examples using Gaia data, and the successful results that were obtained demonstrates that the system behaves as expected.53 p.application/pdfengcc-by-nc-nd (c) Ferran Torra Clotet, 2017http://creativecommons.org/licenses/by-nc-nd/3.0/esAlgorismes computacionalsTreballs de fi de grauAnàlisi multivariableSatèl·lits científicsVia LàctiaComputer algorithmsBachelor's thesesMultivariate analysisScientific satellitesMilky Wayinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
