The geostationary orbit satellite market is experiencing continuous growth, reflecting an increasing demand for telecommunications, meteorology, and Earth observation services. Alongside this growth, there is a rising need to provide maintenance and refueling services to existing satellites without prematurely decommissioning them to a graveyard orbit, where they would be treated as space debris. In recent years, innovative missions have been developed to extend the operational life of Geostationary Earth Orbits (GEO) satellites through in-situ refueling and repairs. This master's thesis develops a new mission concept to enhance the efficiency and sustainability of the process. The proposal entails equipping future generations of satellites with an inflatable robotic arm, designated as PopUp.
