    • Empirical results of a surface-level GNSS-R experiment in a wave channel 

      Carreño Luengo, Hugo; Camps Carmona, Adriano José (2015-06-01)
      Article
      Accés obert
      The scattering of GNSS signals over a water surface is studied when the receiver is at a low height, as in GNSS-R coastal altimetry. The precise determination of the local sea level and wave state from the coast will provide ...

    • Experimental evaluation of GNSS-reflectometry altimetric precision using the P(Y) and C/A signals 

      Carreño Luengo, Hugo; Camps Carmona, Adriano José; Ramos Pérez, Isaac; Rius Jordán, Antonio (2014-05-01)
      Article
      Accés restringit per política de l'editorial
      This work describes a novel dual-band Global Navigation Satellite Systems Reflectometer (GNSS-R) that uses the P(Y) and C/A signals scattered over the sea surface to perform highly precise altimetric measurements. The ...

    • GNSS-R altimeter based on Doppler multi-looking 

      D'Addio, Salvatore; Martín Neira, Manuel; di Bisceglie, Maurizio; Galdi, Carmela; Martín Alemany, Francisco (2014-05-01)
      Article
      Accés restringit per política de l'editorial
      Measuring ocean mesoscale variability is one of the main objectives of next generation satellite altimeters. Current radar altimeters make observations only at the nadir sub-satellite ground track, which is not sufficient ...

    • Optimization and performance analysis of interferometric GNSS-R altimeters: application to the PARIS IoD mission 

      Camps Carmona, Adriano José; Hyuk, Park; Valencia Domènech, Enric; Pascual Biosca, Daniel; Martín Alemany, Francisco; Rius Jordán, Antonio; Ribó Vedrilla, Serni; Benito, Javier; Andres-Beivide, Ana; Saameno, Paula; Staton, Gavin; Martín Neira, Manuel; D'Addio, Salvatore; Willemsen, Philip (2014-05-01)
      Article
      Accés restringit per política de l'editorial
      Reflectometry using Global Navigation Satellite System's signals (GNSS-R) of opportunity was originally conceived in the early 1990 s for mesoscale altimetry, and since then, many studies have shown its applicability to ...
