12.1.5 Errors Compensation

SBAS corrections can be activated for error compensation. If any of the SBAS sys-
tems is activated, the required corrections are calculated and can be applied automati-
cally.
Alternatively, if the SBAS corrections are used as error source, the errors are indica-
ted on each SV by keyword "From SBAS". The errors are internally simulated through
pseudorange errors. The broadcast navigation message cannot be edited; additional
deviations cannot be simulated.
For details on the SBAS correction modes, see

12.2 Atmospheric Effects and Ionospheric Errors Settings

Access:
1. Select "Simulation Configuration" > "Atmosphere".
2. Set the tropospheric and ionospheric models.
For example, select "Ionospheric Model > NeQuick".
The atmospheric configuration comprises the parameters for adjusting the iono-
spheric and tropospheric models of the simulation. The selected model describes
the actual ionospheric and tropospheric models used in the satellite-receiver
channel simulation.
3. To configure the ionospheric navigation parameters that define what the satellites
are transmitting as ionospheric correction parameters, set the ionospheric
parameters on the navigation message of the particular GNSS system:
a) Select "Simulation Configuration > Satellites > GNSS system > SV# > SV Con-
b) Select "SV# > SV Config" > "Copy Modulation Control to SVI-ID = All".
c) Select "Nav Msg Control > Edit".

Ionospheric parameters are read-only and common for all SV of one GNSS
system. To change them, apply the same configuration to all SVs.
