linear acceleration inconsistency

[Jens Noriʇzsɔɥ]

Numeric Integration is not a “well behaving” problem. The uncertainties in the integration constant could quickly add up and lead to the deviations that you observed, see also https://phyphox.org/wiki/index.php/Integ...celeration and the note on “linear acceleration” being a virtual sensor…

The results can be improved if you check for (and subtract) offsets at rest and apply some “knowledge” about the kinematics like velocity or acceleration being zero.
