  • Study of the risk of impact between a spacecraft and space debris 

    Arrufat Jackson, Tomas (Universitat Politècnica de Catalunya, 2013-09)
    Master thesis (pre-Bologna period)
    Open Access
    This work lies in the field of Space Situational Awareness (SSA). Nowadays there is a clear interest within Europe to know in detail the real time distribution of space debris objects orbiting around the Earth. One of the ...
  • The flow over a high-viscosity fluid layer as a drag enhancement technique 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (American Institute of Aeronautics and Astronautics (AIAA), 2017)
    Conference report
    Restricted access - publisher's policy
    It is well known that hydrodynamic drag reduction can be obtained by locally surround-ing an immersed solid boundary with another low viscosity-fluid resulting in a lubricating effect. In aerodynamics propulsion, this ...
  • Theory and modelling of the magnetic field measurement in LISA PathFinder 

    Díaz Aguiló, Marc; García-Berro Montilla, Enrique; Lobo Gutiérrez, José Alberto (2010-01-12)
    Article
    Restricted access - publisher's policy
    The magnetic diagnostics subsystem of the LISA Technology Package (LTP) on board the LISA PathFinder (LPF) spacecraft includes a set of four tri-axial fluxgate magnetometers, intended to measure with high precision the ...
  • The response of an elastic membrane to an external flow as drag enhancement technique 

    Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (American Institute of Aeronautics and Astronautics (AIAA), 2017)
    Conference report
    Restricted access - publisher's policy
    The response of an elastic membrane to an external flow and its significance with regard to aerodynamic drag enhancement technique is discussed. It is shown that because the response of an elastic membrane to an external ...
  • Tools for design of satellite constellations for meteor detection and reentry observation 

    Bertona, Juan Francisco (Universitat Politècnica de Catalunya, 2018-12-13)
    Master thesis
    Open Access
    This thesis presents the necessity and advantages of using a constellation of satellites for the observation of meteors, and of spacecraft and debris reentry.\par For the purposes of evaluating the performance of such ...
  • Trends and patterns in ASIC and FPGA use in space missions and impact in technology roadmaps of the European Space Agency 

    Boada Gardenyes, Roger (Universitat Politècnica de Catalunya / Technische Universiteit Delft, 2011)
    Master thesis (pre-Bologna period)
    Open Access
    ASIC (Application-Specific Integrated Circuit) and FPGA (Field-Programmable Gate Array) are the two most complex and versatile integrated circuit technologies used nowadays in space missions. They are key technologies and ...
