SBAS Corrections Satellite Navigation

3. Select "Satellites > SBAS".
4. Select "Error Correction Mode" > "Generate Corrections Automatically" .
Further settings are not required.
SBAS corrections are calculated and applied
automatically according to the con-
figured errors in the GPS satellites. The broadcast navigation message of the
SBAS satellites and the SBAS corrections cannot be edited.
For example, the long-term correction parameter

error,
where the aggregated clock corrections are calculated as described in "Biases and
corrections" on page 137.
For more information, see "Error Correction Mode" on page 141.
5. If you prefer to change the default settings of the SBAS GEO satellites, perform the
following:
a) Select "SBAS > SV ID > SV Config".
b) Adjust the power and modulation control settings as required.
For description of the related settings, see:
●
Chapter 9.1, "Power Settings" , on page 62
● Chapter 9.2, "Modulation Control Settings" , on page 66
c) Adjust the "Simulated Orbit" and "Simulated Clock" settings of the SV as
required.
You can change the simulated orbit and clock and thus the ranging information
about the GEO satellites itself.
An alternative way to change these parameters is to import different constellation,
see
Chapter 17.2, "Import SBAS Constellation and Correction Data Settings" ,
on page 193.
Applying real SBAS corrections
In the following, we use the default SBAS constellation and correction data. These cor-
rections are real SBAS data, downloaded from the SBAS server and applicable to the
default simulation time (19.02.2014).
1. Enable SBAS.
2. Select "Satellites > SBAS".
