  • Measuring phase scintillation at different frequencies with conventional GNSS receivers operating at 1 Hz 

    Nguyen, Viet Khoi; Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Hai Tung, Ta; The Vinh, La (2019-10-01)
    Article
    Open Access
    Ionospheric scintillation causes rapid fluctuations of measurements from Global Navigation Satellite Systems (GNSSs), thus threatening space-based communication and geolocation services. The phenomenon is most intense in ...

    External research report
    Open Access
    In the three preceding papers in the series, we presented a model dealing with the global and small-scale structure and kinematics of hierarchically assembled, virialised, collisionless systems, which correctly accounted ...
  • Revisit the calibration errors on experimental slant total electron content (TEC) determined with GPS 

    Nie, Wenfeng; Xu, Tianhe; Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Chen, Wu; Xu, Guochang (2018-06-26)
    Article
    Open Access
    The calibration errors on experimental slant total electron content (TEC) determined with global positioning system (GPS) observations is revisited. Instead of the analysis of the calibration errors on the carrier phase ...
