Saving RINEX Data
[For more information on theRINEX data format, refer to e.g., Wikipedia: RINEX.]
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). 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.
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>
After each six hours or when the scenario is stopped, the navigation data is saved to:
/observations/scenarioNameYYYYMMDDHHMMSS.nav
The generated files can be retrieved via GSG StudioView, the Web UI, or by using SCPI commands (see MMEMory:COPY).
Additionally, a link named /observations/latest.nav
points to the latest generated file.
The files are in RINEX 3.0.2 mixed format. As the unit generates new navigation data sets quite rarely, it is recommended that navigation data logging is enabled before starting a scenario. Navigation data logging is turned off when scenario stops.
