Processing the Logs
Log files are stored on SD card as binary files and they're encoded. However, you can extract the data to understandable text format, basically it's
CSV format which can be later exported in XLS or Matlab or anything else for post-processing and analysis.
You'll need to use the following Python script: ulog2csv.py
Python should be installed on your computer.
If you don't have it yet you can download here https://www.python.org/downloads/ , version 2.7.
To export the log follow the steps:
Open command line
Go to the folder where ulog2csv.py script is located
cd /path/to/script
Execute the command:
python ulog2csv.py filename.ulg
where filename.ulg is the path to the log file
You'll see the folder will all log messages splitted in separate files
For instance, if you're interested in GNSS (GPS/GLONASS) data you would need GNSS_REPORT.csv file.
