  • An acoustic technique for propellant gauging 

    Fili, Thomas; Quintana Buil, Guillem; González Cinca, Ricardo (2022)
    Conference report
    Restricted access - publisher's policy
    The gauging of propellants in upper stages or satellites in orbit is a challenging task due to the absence of buoyancy, which makes liquids and gases adopt a large variety of configurations. The new Spectral Mass Gauging ...

  • Heat transfer management in propellant tanks 

    Quintana Buil, Guillem; González Cinca, Ricardo (2022)
    Conference report
    Restricted access - publisher's policy
    A critical issue in long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, and hot spots might appear on the tank walls ...

  • Integrated acoustic technology for boil-off control, mass gauging, and structural health monitoring in cryogenic fuel tanks 

    Quintana Buil, Guillem; Abecia Hernanz, Sara Cecilia; Mangram, William; Khasin, Michael; Chang, Fu Kuo; González Cinca, Ricardo (2022)
    Conference report
    Restricted access - publisher's policy
    Long-term space exploration missions require efficient systems for cryogenic propellant storage and management. The exposure of the fuel tanks to the in-space operational environment implies the need for efficient technologies ...

  • The Mechanism for GNSS-Based Kinematic Positioning Degradation at High-Latitudes Under the March 2015 Great Storm 

    Nie, Wenfeng; Rovira Garcia, Adrià; Li, Mowen; Fang, Zhenlong; Wang, Yong; Zheng, Dunyong; Xu, Tianhe (2022-06)
    Article
    Open Access
    In this study, we focus on the kinematic precise point positioning (PPP) solutions at high-latitudes during the March 2015 great geomagnetic storm. We aim to discover the mechanism behind the positioning degradation from ...

  • Volcanic eruption of Cumbre Vieja, La Palma, Spain: A first insight to the particulate matter injected in the troposphere 

    Sicard, Michaël; Cordoba Jabonero, Carmen; Barreto Velasco, África; Welton, Ellsworth J.; Gil Díaz, Cristina; Carvajal Pérez, Clara Violeta; Comerón Tejero, Adolfo; García Rodríguez, Omaira; Muñoz Porcar, Constantino; Rodríguez Gómez, Alejandro Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-20)
    Article
    Open Access
    The volcanic eruption of Cumbre Vieja (La Palma Island, Spain), started on 19 September 2021 and was declared terminated on 25 December 2021. A complete set of aerosol measurements were deployed around the volcano within ...

  • Interferometric SAR deformation timeseries: a quality index 

    Abera Wassie, Yismaw; Mirmazloumi, Seyedmohammad; Monserrat Hernández, Oriol; Crippa, Bruno; Palamá, Riccardo; Barra, Anna; Crosetto, Michele (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2021)
    Conference report
    Open Access
    Estimating unknown absolute phase from a wrapped observation is a challenging and ill-posed problem that possibly leads to misinterpretation of interferometric SAR (InSAR) deformation results. In this study, we introduce ...

  • Status and trends of wetland studies in Canada using remote sensing technology with a focus on wetland classification: a bibliographic analysis 

    Mirmazloumi, Seyedmohammad; Brisco, Brian (Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-09)
    Article
    Open Access
    A large portion of Canada is covered by wetlands; mapping and monitoring them is of great importance for various applications. In this regard, Remote Sensing (RS) technology has been widely employed for wetland studies in ...

  • A secure broadcast service for LDACS with an application to secure GBAS 

    Maurer, Nils; Caamaño Albuerne, María; Gerbeth, Daniel; Graupl, Thomas; Schmitt, Corinna (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Conference report
    Open Access
    The VHF Data Broadcast (VDB) data link is responsible for transmitting Ground Based Augmentation System (GBAS) corrections from the GBAS ground station to the aircraft. Thus, it is a major bottleneck for the evolution and ...

  • LES study of the impact of fuel composition on a swirl spray flame approaching blow-off 

    Both, Ambrus; Mira, Daniel; Lehmkuhl Barba, Oriol (2021)
    Conference lecture
    Open Access
    The present paper focuses on the large eddy simulation (LES) of the n-heptane and n-dodecane flames of the Cambridge swirl flames data repository (Sidey et al., 2017). The applied tabulated chemistry spray combustion model ...

  • Assessment of chemistry reduction in high-pressure spray flames of oxymethylene ethers using large-eddy simulations

    Conference lecture
    Open Access
    This study is focused on the numerical investigation of reduced chemical schemes for high pressure spray flames of oxymethylene ethers (OMEx). A reduced mechanism using Path Flux Analysis (PFA) technique is tested using ...

  • Detection of GNSS multipath with time-differenced code-minus-carrier for land-based applications 

    Caamaño Albuerne, María; Garcia Crespillo, Omar; Gerbeth, Daniel; Grosch, Anja (IEEE Press ; Wiley, 2020)
    Conference report
    Open Access
    Ground transportation systems demand accurate and robust localizationfunctions. Satellite navigation is considered a key element in those systems, but its position determination can be highly corrupted in urban environments ...
