Calibration and compensation of inertial sensor errors in portable applications — a review

Measurements based on inertial sensors are increasingly applied in daily life. The biggest problem plaguing such sensors is its large errors. In typical environments of portable applications, most calibrating equipments and methodologies designed for general inertial navigation systems are no longer suitable. Therefore, new calibration and compensation methods tailored to portable applications need to be explored. This paper makes a survey of the recent studies in this field, describing typical solutions to portable calibration and compensation of inertial measurement errors, with comparisons of their advantages and limitations when possible.
