consumer-grade IMUs are still well below the performance of even much older military-grade IMUs (which tend to be impressive feats of precision engineering with pricetags to match, but also physically much larger). You'll still find anything that's useful for working out position over any time period is export-controlled (dual-use or stricter).

That's super interesting to learn, thanks for letting me know! I'm a software guy but I love learning about sensors, it's always amazing.
