Using the GSG Web UI on a connected PC, click on GSG FILES , then navigate to
observations , and click on executionlog.txt .
The maximum size of the execution log file is 20,000 lines. Once the limit is reached, the
oldest entries will be overwritten by new data.
Please note that the log is not updated in real time, but is updated when a scenario stops,
for
example.
Also note that the log will be deleted when a Clean & Restore operation is performed, i.e.
when restoring the unit to factory default configuration ( Options > Reset to factory
defaults ).

Saving RINEX Observation Data
It is possible to store RINEX observations of a running scenario. This feature can be
enabled using the SCPI command:
SOURce:SCENario:OBS <start>,<duration>,<interval>
<start>
Specifies the number of seconds since scenario start to expire before starting to
log observations. Using the parameter ‘-1’ will start the logging of a running simulation
immediately.
<duration>
The observation period in seconds. Using the parameter '-1' will log until the
end of the scenario.
<interval>
Is the sample rate.
After the duration/hour is passed or the scenario is stopped, the observations are saved to:
/observations/scenarioNameYYYYMMDDHHMMSS.obs
Each file can contain at maximum 1 hour of data. The generated files can be retrieved via
GSG StudioView , the Web UI, or by using SCPI commands (see "MMEMory:COPY" on
page 321 ). Additionally, a link named
/observations/latest.obs
points to the latest
generated file.
Observation files supported include GPS, GLONASS, Galileo, BeiDou and mixed. The
RINEX file can be used in post-processing with the navigation data obtained from receiver.
Saving RINEX Navigation Data
It is also possible to log RINEX navigation data for a running scenario. This feature can be
enabled using the SCPI command:
SOURce:SCENario:NAV <ON|OFF>
