Accessing raw flight data

I have need to do some independent validation of flight performance. I have found several post flight visualization tool that will export filtered data, or present raw data, but none that will export the raw gyro,acc,baro data itself.

Several posts point to dead 404 links.

How can I get access to raw data?

Is this for PX4? So you want to look at ulog data? .ulg files?

Yes. We need the raw ACC and GYRO for our independent validation requirements.

And you have considered using GitHub - PX4/pyulog: Python module & scripts for ULog files?

Yes, as well as one of the interactive viewers.

The python created individual xsl files for each of the aggregates post processed trends, but did not greater a raw file.

The viewer presented all the aggregated trends as well as the understanding raw data. It allows for export of the post processed data, but we saw no option to export the raw data.

It is in there, just missing how to export it…

I’m trying to assess if the PX4 ecosystem is open with its data.

It looks like its not.

If anyone has any tool to get at raw data please extend this post as it will help others. Unfortunately I have to move to another ecosystem.

Best with all your efforts!

The ulg format is described here: ULog File Format | PX4 Guide (main)

If the existing tooling doesn’t fit your needs, just write your own.
