  • Feasibility of precise navigation in high and low latitude regions under scintillation conditions 

    Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Rovira Garcia, Adrià; Camps Carmona, Adriano José; Riba Sagarra, Jaume; Barbosa, José; Blanch Llosa, Estefania; Altadill, David; Orús Pérez, Raul (2018-02-06)
    Article
    Open Access
    Scintillation is one of the most challenging problems in Global Navigation Satellite Systems (GNSS) navigation. This phenomenon appears when the radio signal passes through ionospheric irregularities. These irregularities ...

  • The impacts of the ionospheric observable and mathematical model on the Global Ionosphere Model 

    Nie, Wenfeng; Xu, Tianhe; Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Chen, Wu; Xu, Guochang (2018-02-01)
    Article
    Open Access
    A high-accuracy Global Ionosphere Model (GIM) is significant for precise positioning and navigating with the Global Navigation Satellite System (GNSS), as well as space weather applications. To obtain a precise GIM, it is ...

  • AATR an ionospheric activity indicator specifically based on GNSS measurements 

    Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Rovira Garcia, Adrià; González Casado, Guillermo; Ibáñez Segura, Deimos; Orús Pérez, Raul (2018-03-01)
    Article
    Open Access
    This work reviews an ionospheric activity indicator useful for identifying disturbed periods affecting the performance of Global Navigation Satellite System (GNSS). This index is based in the Along Arc TEC Rate (AATR) and ...

  • GPS differential code biases determination: methodology and analysis 

    Sanz Subirana, Jaume; Juan Zornoza, José Miguel; Rovira Garcia, Adrià; González Casado, Guillermo (2017-10)
    Article
    Restricted access - publisher's policy
    We address two main problems related to the receiver and satellite differential code biases (DCBs) determination. The first issue concerns the drifts and jumps experienced by the DCB determinations of the International ...

  • Eccentricity samples: implications on the potential and the velocity distribution 

    Cubarsí Morera, Rafael; Stojanovic, Milan; Ninkovic, Slobodan (2017)
    Article
    Open Access
    Planar and vertical epicycle frequencies and local angular velocity are related to the derivatives up to the second order of the local potential and can be used to test the shape of the potential from stellar disc samples. ...

  • Intrinsic functional and architectonic heterogeneity of tumor-targeted protein nanoparticles 

    Peasarrodona, Mireia; Crosas, Eva; Cubarsí Morera, Rafael; Vazquez, Esther; Villaverde, Antonio; et al., . (2017-04)
    Article
    Open Access
    Self-assembling proteins are gaining attention as building blocks for application-tailored nanoscale materials. This is mostly due to the biocompatibility, biodegradability, and functional versatility of peptide chains. ...

  • The Stanford-ESA integrity diagram: focusing on SBAS integrity 

    Tossaint, Michel Mathias Maria; Samson, Jaron; Toran, Felix; Ventura Traveset, Javier; Sanz Subirana, Jaume; Hernández Pajares, Manuel; Juan Zornoza, José Miguel (ION Publications (The Institute of navigation), 2016)
    Conference lecture
    Restricted access - publisher's policy
    In this article, a new concept for SBAS integrity validation is presented. The proposed concept is a modification of the well known Stanford diagram [2], where a 2D histogram shows the relationship of position errors against ...
