The European Commission has recently released the official document describing the particular ionospheric model
developed for the Galileo satellite navigation system. Such publication allows GNSS receiver manufacturers starting the
implementation of the specific algorithm targeted for their Galileo related products in order to be compliant with the Galileo
system. According to the European GNSS (Galileo) Open Service Signal In Space Interface Control Document, Issue 1.1, among
the parameters that are broadcast in the Galileo navigation message, parameters that are sent within both F/NAV and I/NAV,
one can find five Ionospheric Disturbance Flags for Regions 1 to 5 (SF1, SF2, SF3, SF4 and SF5 respectively). Nevertheless,
in the current version of the model presented in the Galileo-Iono document, the Ionospheric Disturbance flags are not used
within the Galileo ionospheric correction calculation. In this work, a potential approach to account for this information is
being investigated. This plan includes the update of the Galileo ionospheric, NeQuick-G, correction model by specifying the use
of these flags. Hence a customized version of the NeQuick-G model has been developed and tested.
