Recording Data with StudioView
StudioView's Data Recorder allows to obtain all required data automatically without the need to execute SCPI commands. The Data Recorder generates NMEA data from the trajectory currently being played on the GSG unit, collecting RINEX navigation and observation data, recording RSG parameters, satellites information and navigation messages.
The data can be retrieved either by using the GSG Web Interface, or via SCPI commands, or by using Studioview.
Using the StudioView Data Recorder for the First Time
To open the Data Recorder, navigate to Tools > Data Recorder, or click :
StudioView's Data Recorder
Under the Data tab you decide where the data to be recorded comes from (a GSG unit, or a GNSS receiver), and which data to log:
- RINEX navigation files
- RINEX observation files
- NMEA from GSG unit
- NMEA from connected receiver (This can be used to record NMEA data for the GSG Record and Playback option.)
You can also redirect NMEA data via a serial port, or – in case of Receiver data – to a GSG unit.
On the left side of the screen:
- Check the box GSG unit, then click to configure the connection (for details, see Connecting StudioView to GSG.)
- Choose which data to record: Navigation data, Observations, RSG data, Satellites data (e.g., satellite position, Doppler shift, etc), navigation messages.
- As an option, the NMEA data can also be redirected to a serial port e.g., to use it with a device that utilizes real-time NMEA data (such as a marine plotter). If so desired, select and configure the port to be used to redirect the data.
Select Output files for each recorded data category.
On the right side of the screen:
- Select Receiver if you have a GNSS receiver connected to your StudioView computer, and you want to record the life sky data it reads while e.g., driving a car
- Select and configure the Serial port (if in doubt, use the default settings)
- Select the type of Receiver chip: If you have a SiRF chip, StudioView will configure this receiver automatically.
- Select an Output file for the recorded NMEA data that the receiver sees.
- If so desired, you can not only record the generated data, but also redirect it to a different serial port of your computer e.g., to consume the data with a third-party application. If applicable, select and configure that port.
- As an option, the NMEA data can also be redirected to a GSG unit, in order to use it with a device that utilizes real-time NMEA data (e.g., a marine plotter or receiver demo software).
Note that GSG does not accept real-time NMEA data, only planned NMEA trajectory data. When redirecting NMEA data to a GSG unit, StudioView actually converts the NMEA data to RSG commands prior to sending the data.
- Select which data to send to the GSG unit. If the receiver does not send GGA data, i.e. the data stream does not include any altitude information (as is the case with RMC data), you may set a predefined altitude.
To configure this feature, click (for details, see Connecting StudioView to GSG.)
Recording the Data
Now, that the configuration is complete, click and begin with your test drive.
Or, load the desired scenario on your GSG unit, and click .
DO NOT start the scenario via the GSG unit, since the RINEX navigation data will not be captured! (Unless you manually submitted the SCPI navigation data logging command.)
Once data starts to be generated, the Data Recorder will display the incoming raw data in the bottom section of the Data tab. Under the View tab (top-left corner of the screen) you can also visually display the progress in real-time on the Google Map and see a skyplot with all visible satellites, as well as velocity and altitude charts.
