How to use Pixhawk / Cube only for data fusion and output GGA data frame


Does my question of last week not make sens ? I would want to know if it exists a documentation allowing to set up the pixhawk as a datalogger of trajectory data including the data fusion between GNSS data and computed positions based on motion sensors with a real time output of these data to an external computer to tag measures of specific sensors. It would be an interesting solution to insure positioning with sufficient accuracy during canyoning effect of few seconds.

I hope my question is clearer. I have changed too the category, maybe it is more appropriate.

Thank you.
