N2 - This paper calibrates deterministic errors in accelerometer data from 20 commercial Movella DOT IMUs across four institutions. Applying Jeff Ferguson’s calibration of deterministic errors through a six-point tumble test, we assess accuracy and precision. The results show fixed bias/offset as the dominant error, with larger errors in the z axis. Calibration significantly improves precision and accuracy for gravity-aligned measurements, regardless of institution or axis. Although less effective near-zero values due to sensor sensitivity, this research confirms the method’s effectiveness for enhancing IMU data reliability.
