I saw recently the blog post about GPS loggers: https://www.trekview.org/blog/2020/gps-101/
It got me thinking about the IMU in phones.
Are these better than those in cameras?
If they are, would it be possible to add IMU data (like pitch, roll, yaw, etc) to a photo and video file like described with a GPS log.
I know this would be useful for the GoPro Fusion I have, because these values are not reported in timelapse photo mode.
