    Global Navigation Satellite System Reflectometry and L-band microwave radiometry have been used for soil moisture, biomass, and cryosphere studies. Combining both technologies in a low-power and cost-effective solution ...

  • Efficient aeroelastic analysis of wind loads on inflatable hangars 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique (International Centre for Numerical Methods in Engineering (CIMNE), 2019)
    Conference report
    Open Access
    Wind loads play a crucial role in inflatable structures. Unfortunately, design loads from safety regulations grossly overestimate the real aerodynamic forces. Thus, a more accurate estimation of wind loads is desirable. ...

  • SOAR - Satellite for Orbital Aerodynamics Research 

    Crisp, Nicholas H.; Roberts, Peter C.E; Edmonson, Steve; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (International Astronautical Federation, 2018)
    Conference report
    Restricted access - publisher's policy
    SOAR (Satellite for Orbital Aerodynamics Research) is a CubeSat mission designed to investigate the interaction betweendifferent materials and the atmospheric flow regime in Very Low Earth Orbits (VLEO) and to demonstrate ...

  • Advances on the Inductive Plasma Thruster Design for an Atmosphere-Breathing EP System 

    Romano, Francesco; Herdrichd, Georg H.; Boxberger, Adam; Rodríguez Donaire, Silvia; García-Almiñana, Daniel; Sureda Anfres, Miquel (International Astronautical Federation, 2018)
    Conference report
    Restricted access - publisher's policy
    Challenging space mission scenarios include those in very low Earth orbits, where the atmosphere creates significant drag to the S/C and forces their orbit to an early decay. For drag compensation, propulsion systems are ...

  • A Review and Gap Analysis of Exploiting Aerodynamic Forces as a Means to Control Satellite Formation Flight 

    Traub, Constantin; Romano, F.; Binder, Tilman; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (2018)
    Conference report
    Restricted access - publisher's policy
    Using several small, unconnected satellites flying in formation rather than a single monolithic satellite has many advantages. As an example, separate optical systems can be combined to function as a single larger (synthetic) ...

  • Effects of applied magnetic field on IPG6-S, test-bed for an ABEP-based inductive plasma thruster (IPT) 

    Romano, Francesco; Herdrich, Georg; Binder, Tilman; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (Association Aéronautique et Astronautique de France, 2018)
    Conference report
    Restricted access - publisher's policy
    An atmosphere-breathing electric propulsion system (ABEP) captures the residual atmosphere of a planet and uses it as propellant for an electric thruster to counteract the drag. The system would theoretically allow orbiting ...

  • Fluidic actuator performance variation via internal dimensions modifications 

    Baghaei, Masoud; Bergadà Granyó, Josep Maria; Campo Sud, David del (2017)
    Conference report
    Restricted access - publisher's policy
    When aimed to modify the downstream vortex shedding of a given bluff body, whether any road vehicle or wing profile, the use of Active Flow Control (AFC) appears to be an efficient technology. Among the different (AFC) ...

  • Research on fluidic amplifiers dimensional modifications via computer simulation (CFD) 

    Baghaei, Masoud; Bergadà Granyó, Josep Maria; Campo Sud, David del; Campo Gatell, Vanessa del (Istanbul Tecnical University, 2016)
    Conference report
    Restricted access - publisher's policy
    When studying active flow control applications, it is already stated that activating the boundary layer via using periodic flow produces better performance than when employing steady blowing or sucking. This is why studying ...

  • Successes and challenges of a collaborative-PBL program in engineering degrees 

    González Vila, Joaquin; Font Andreu, Jorge; Salán Ballesteros, Maria Núria; García-Almiñana, Daniel; Ortiz Marzo, José Antonio; Mudarra López, Miguel; Griful Ponsati, Eulàlia (2012-02-02)
    Conference report
    Open Access
    This paper presents an extracurricular program called INSPIRE3 that has been implemented by the ETSEIAT (Escola Tècnica Superior d’Enginyeries Industrial i Aeronàutica de Terrassa), a center belonging to the UPC-BarcelonaTech ...

  • Review of Lambert's problem 

    Torre Sangrà, David de la; Fantino, Elena (2015)
    Conference lecture
    Open Access
    Lambert’s problem is the orbital boundary-value problem constrained by two points and elapsed time. It is one of the most extensively studied problems in celestial mechanics and astrodynamics, and, as such, it has always ...

  • Analysis of perturbations and station-keeping requirements in highly-inclined geosynchronous orbits 

    Fantino, Elena; Flores Le Roux, Roberto Maurice; Di Salvo, Alessio; Di Carlo, Marilena (2015)
    Conference report
    Open Access
    There is a demand for communications services at high latitudes that is not well served by conventional geostationary satellites. Alternatives using low-altitude orbits require too large constellations. Other options are ...

  • Modelling harmonics drawn by nonlinear loads 

    Lamich Arocas, Manuel; Balcells Sendra, Josep; Mon González, Juan; Corbalán Fuertes, Montserrat; Griful Ponsati, Eulàlia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Restricted access - publisher's policy
    This paper is devoted to obtain a model of nonlinear loads (NLL) connected to LV electric networks, in order to predict the consequences of including parallel active or passive filters. The model is based on Neural ...
