    Signals from a Global Navigation Satellite System (GNSS) can be disturbed along the propagation ray path from the satellites to the receivers. The presence of irregularities in the electron density in the near-Earth space ...
  • Assessment of Ionospheric Corrections Algorithms Using the GNSS Laboratory Tool Suite (gLAB): From STEC to Navigation Performance 

    Aragón Ángel, Maria Angeles; Rovira Garcia, Adrià; Ibáñez Segura, Deimos (ION Publications (The Institute of navigation), 2020)
    Conference report
    Restricted access - publisher's policy
    Users of the Global Navigation Satellite System (GNSS) using a single-frequency receiver need to use an Ionospheric Correction Algorithm (ICA) to compensate the delay introduced by the Ionosphere on radio waves. The European ...
