Binary File format

Hello,

Were can I find the documentation on the binary file format that can be downloaded from the sub in QGroundControl.

I would like to access the raw data from each mission in particular the 9-axis accelerometer data to see if I can get a reasonable INS solution from it.

Regards,

Alan

Unfortunately, I don’t think the format is documented anywhere. You can use mavlogdump.py to export the data to csv or m files and MAVExplorer.py to plot the data. These programs are included in a Mavproxy installation.

The source code for the log format is here.

Thanks Jacob,

I’ll have a crack at decoding the bin file with the source you provided.
I will repost my code if I get a decoder working
