Experimental analysis of IMU under vibration

MEMS-based Inertial Measurement Units are today widely employed in many contexts. Especially in the field of self-driving vehicles and navigation they provide important information to the electronic control units for implementing positioning, localization and tracking algorithms. As a consequence, it becomes important to analyse the accuracy, reliability and time to failure of such systems when operating in conditions as more as possible similar to ones experienceable in the practice. To these aims, in this paper we investigate on IMU performance under random vibration which can be thought of as a kind of stress to which IMUs are continuously interested during their common operating. The experimental results have proved that these devices are very sensitive to the considered conditions and that suitable measurement procedures and measurement setup should be designed for the IMUs performance analysis.
