Single frequency receivers need to apply a model to remove the ionospheric refraction, which can reach up to few tens of meters, depending on the elevation of rays and the ionospheric conditions.

The models used in GPS and Galileo are described in Klobuchar Ionospheric Model and NeQuick Ionospheric Model. The GPS/Galileo satellites broadcast the parameters needed to run these ionospheric models.

In GLONASS, there is no ionospheric model applied and thus, there is no broadcast of any parameter. However, any of the GPS or GALILEO ionospheric models could be used for GLONASS signals, by applying a correction factor given by their relative squared frequencies ratio.
