DOI: 10.1109/tim.2021.3127629
Abstract: Redundant inertial sensor systems improve navigation performance and guarantee fault detection or fault isolation functions. However, they may cause unexpected side effects owing to their enlarged size. The misalignment between the center of gravity of… read more here.
