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).
To export the log, follow these simple steps:
- Open command line
- Go to the folder where " ulog2csv.py " script is located
- Execute the command:
python ulog2csv.py 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.
