      Conference report
      Restricted access - publisher's policy
      This contribution presents the assessment, on both the maximum electron density (NmF2) and the corresponding peak height of the F2 layer (hmF2), of the overall performance of such ionospheric key parameters inferred from ...
    • High-resolution ionosphere corrections for single-frequency positioning 

      Goss, Andreas; Hernández Pajares, Manuel; Schmidt, Michael; Roma Dollase, David; Erdogan, Eren; Seitz, Florian (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-01)
      Article
      Open Access
      The ionosphere is one of the main error sources in positioning and navigation; thus, information about the ionosphere is mandatory for precise modern Global Navigation Satellite System (GNSS) applications. The International ...
