MEMS Inertial Measurement Unit Calibration Using Low Cost Hardware

The Inertial Measurement Unit (IMU) is a collection of inertial sensors that typically includes three accelerometers and three rate gyros. It can detect changes in motion along any of its three axes. Because these inertial sensors are susceptible to a variety of noise effects, a six-position calibration method is frequently employed to quantify deterministic sensor errors. However, for the standard six-position static test calibration technique, a high-precision turntable is required, which is relatively expensive and fixed in place, rendering it inaccessible to many research groups and for use as a portable instrument. As a result, this work provides a low-cost six-position static test approach employing low-cost hardware and an Arduino board. Without the use of any supplementary equipment, this approach may still retain the efficacy of IMU calibration.
