Calf-INS: A Calf-Mounted IMU-based Inertial Navigation System for Pedestrian

open access: yes, 2023
<p>Pedestrian dead reckoning based on a wearable inertial measurement unit (IMU) is an important part of the pedestrian positioning system because it is not affected by the external environment. However, step model-based methods have the problems of low positioning performance, and zerovelocity update (ZUPT) based methods (i.e., foot-mounted ...
