The Space Tug is a spacecraft capable of transferring satellites between various orbits, performing repair operations on orbiting vehicles, and removing satellites at the end of their mission. The research focuses on analysing the ΔV required for orbital manoeuvres of two missions: one in LEO orbit for the removal of satellites from more crowded orbits, and one in GEO orbit for moving satellites into graveyard orbits. Using the General Mission Analysis Tool (GMAT) software transfer orbits are simulated, the results are analyzed and the optimal trajectories for specific missions are identified. The findings provide important insights into the advantages and limitations of various transfer orbits, offering guidelines for future Space Tug missions.
Lo Space Tug è un veicolo spaziale in grado di effettuare trasferimenti di satelliti tra varie orbite, operazioni di riparazione per i veicoli in orbita e la rimozione di satelliti a fine missione. La ricerca si focalizza sull'analisi del ΔV necessario per manovre orbitali di due missioni: una in orbita LEO per la rimozione di satelliti da orbite più affollate e una in orbita GEO per lo spostamento di satelliti in orbite cimitero. Tramite l'utilizzo del software GMAT (General Mission Analysis Tool) si simulano le orbite di trasferimento, si analizzano i risultati e si identificano le traiettorie ottimali per specifiche missioni. I risultati forniscono importanti informazioni sui vantaggi e le limitazioni delle varie orbite di trasferimento, offrendo delle linee guida per future missioni di Space Tug.

Abstract
The Space Tug is a spacecraft capable of transferring satellites between various orbits, performing repair operations on orbiting vehicles, and removing satellites at the end of their mission. The research focuses on analysing the ΔV required for orbital manoeuvres of two missions: one in LEO orbit for the removal of satellites from more crowded orbits, and one in GEO orbit for moving satellites into graveyard orbits. Using the General Mission Analysis Tool (GMAT) software transfer orbits are simulated, the results are analyzed and the optimal trajectories for specific missions are identified. The findings provide important insights into the advantages and limitations of various transfer orbits, offering guidelines for future Space Tug missions.| File | Dimensione | Formato | |
