    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
    Accés obert
    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
    Accés obert
    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
    Accés obert
    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. ...

  • A method for scintillation characterization using geodetic receivers operating at 1 Hz 

    Juan Zornoza, José Miguel; Aragón Ángel, Maria Angeles; Sanz Subirana, Jaume; González Casado, Guillermo; Rovira Garcia, Adrià (2017-05-08)
    Article
    Accés restringit per política de l'editorial
    Ionospheric scintillation produces strong disruptive effects on global navigation satellite system (GNSS) signals, ranging from degrading performances to rendering these signals useless for accurate navigation. The current ...
