Processing the Logs

Log files are stored on the SD card as binary files and they're encoded for security reasons. However, you can extract the data and view it in a understandable text format (CSV format which can be later exported in XLS, Matlab, or anything else for post-processing and analysis).

You'll need to use the following Python script:

Python should be installed on your computer.

If you don't have Python, you can download it here, version 2.7.

To export the log, follow these simple steps:

  • Open command line

  • Go to the folder where " " script is located cd /path/to/script

  • Execute the command:

    python filename.ulg

    (filename.ulg is the path to the log file)

  • You'll see the folder will all log messages split in separate files

For instance, if you're interested in GNSS (GPS/GLONASS) data you would need GNSS_REPORT.csv file.
