Ah, they're doing sensor fusion with inbuilt IMUs? That makes sense... I have a colleague with some deep technical knowledge in this area - he's the guy who did the heavy lifting when I built an inertial mocap suit a while ago. I've pointed him at your project. If it turns out that it is of interest, perhaps you can get some useful collaboration / suggestions out of that!
