  • Design of a solar sail as the propulsion system for a nanosatellite 

    Rique Garaizar, Orzuri (Universitat Politècnica de Catalunya, 2013-06)
    Master thesis (pre-Bologna period)
    Open Access
    This project presents the design of a solar sail as a feasible solution to thrust nanosatellites. A solar sail is a high-energy space propulsion system that uses solar radiation pressure to push large ultra-thin mirror to ...
  • Study of advanced materials for thermal insulation in the inner Solar System 

    Miró Jané, Arnau (Universitat Politècnica de Catalunya, 2014-09)
    Master thesis (pre-Bologna period)
    Open Access
    Space harsh environmental condition often calls for an adequate thermal regulation and insulation. In this thesis, a thermal model for a greenhouse in Mars is presented. Its objectives are to achieve and maintain suitable ...
  • Study of a lunar satellite navigation system 

    Saura Carretero, Gemma (Universitat Politècnica de Catalunya, 2012-09)
    Master thesis (pre-Bologna period)
    Open Access
    The objective of the present study is to hold a preliminary analysis and design of a lunar global satellite navigation system able to provide accurate positional information to operators on the surface or in low lunar ...
  • Study of Earth-Moon trajectories with solar sail propulsion 

    Canales García, David (Universitat Politècnica de Catalunya, 2014-09)
    Master thesis (pre-Bologna period)
    Open Access
    The computation of Earth-to-Moon trajectories constitutes an important and interesting chapter of spacecraft trajectory design. The traditional techniques based on Hohmann maneuvers and patched conics allowed the fast ...
  • Study of Earth-to-Mars transfers with low-thrust propulsion 

    López Hellín, Xavi (Universitat Politècnica de Catalunya, 2011-09)
    Master thesis (pre-Bologna period)
    Open Access
    Knowledge and investigation about low-thrust propulsion systems have been increasing during the last years and some spacecrafts employing this technology have succeeded in their objectives, which contribute to the possible ...
  • Study of end-of-life disposal options for highly-inclined geosynchronous satellites 

    Cabot Costa, Elisabeth (Universitat Politècnica de Catalunya, 2016-06)
    Bachelor thesis
    Open Access
    In recent years, the growing volume of activities in the northern regions (Arctic, Canada, Northern Russia) has produced an increasing request for communications services. Several studies have concluded that there are ...
  • Study of spacecraft orbits in the gravity field of the moon 

    Cardoso Vilana, Edgar (Universitat Politècnica de Catalunya, 2012-01)
    Master thesis (pre-Bologna period)
    Open Access
    The objective of the present study is to analyze the evolution of low lunar orbits under the gravitational potential of the Moon and additional perturbations of gravitational (Earth and Sun gravity) and non-gravitational ...
  • Study of the Martian environment for application to the design of a greenhouse 

    Torre Sangrà, David de la (Universitat Politècnica de Catalunya, 2014-07)
    Master thesis (pre-Bologna period)
    Open Access
    The human exploration of Mars belongs to the current plans of NASA and ESA. Getting the astronauts to Mars and returning them safely to Earth imposes several engineering challenges. In particular, creating the conditions ...
  • Study of the mechanical response of the LTP's test masses due to the action of control heaters in LISA Pathfinder 

    Gibert Gutiérrez, Ferran (Universitat Politècnica de Catalunya, 2011-01)
    Master thesis (pre-Bologna period)
    Open Access
    The main aim of the LISA Pathfinder (LPF) mission is to place two Test Masses into a very stable drag free environment and make very precise interferometric measurements of displacements between them. In order to achieve ...
  • Study of the optimal approach and detection phases for missions to small asteroids 

    Pacheco Fuentes, Adrià (Universitat Politècnica de Catalunya, 2015-01)
    Master thesis (pre-Bologna period)
    Open Access
    Nowadays, small asteroids are catching the space community’s attention and interest. Instead of planning expensive missions to planets, missions to small asteroids (<100m) are of interest both because of their lower costs ...
  • Study of the performance of an inertial measurement unit on board a launcher 

    Laguna Benet, Xavier (Universitat Politècnica de Catalunya, 2014-03)
    Master thesis (pre-Bologna period)
    Open Access
    Current predictions indicate that by 2020 the available launchers will not cover the market niche of small satellites. The Aldebaran launcher is intended to cover this market niche. Aldebaran will perform an aerial launch ...
