Satellite Navigation
d) Select "Nav Msg Content > Config > Ionosphere".
Per default, the navigation message parameters are set to values, that correspond
to the values retrieved from the constellation data source and selected atmospheric
model.
Changing these values leads to deviation between the simulated and the broad-
casted navigation message and thus deliberated errors. SBAS corrections can be
activated for error compensation.
Available navigation message parameters depend GNSS system and selected
navigation message type.

For GPS satellites, for example, the navigation message carries the parameters
describing the Klobuchar ionospheric model, see

The ionospheric model for GLONASS is not yet specified; its satellites transmit
no data on the atmosphere.
GPS, Galileo and BeiDou assume specific ionospheric models. These systems
transmit different atmospheric navigation parameters.
