摘要: Pedestrian navigation especially indoors suffers from the unavailability of useful GNSS signals for positioning. Alternatively, a low-cost Inertial Measurement Unit (IMU) positioning system that does not depend on signal can be used indoor navigation. However its performance is still compromised because fast-accumulating heading drift error affecting such IMU sensor. This results in huge when navigating more than few seconds using only In this study, real field trials are presented foot-mounted rotated single axis. Two promising have been obtained. First, it mitigates significantly and second, increases observability z-axis gyro bias error. has resulted greatly reduced position pedestrian system.
