SBAS message scheduling
The SBAS messages are scheduled according to a user-defined period. The default
values reflect the timeouts specified in the specification
.
Loading historical data
Similar to the constellation and navigation data files, you can load SBAS constellation
and correction files, for example, to reproduce a specific situation form the past.

13.2 About Errors Correction
When to use SBAS corrections?
As general rule, apply SBAS corrections,
if errors are simulated
. If the simulated and
the broadcasted navigation messages match as it is in the default configuration, SBAS
corrections are not necessary. In this case, activating SBAS does not improve the posi-
