A motion-pattern learning and state-aware compensation method for GNSS-denied three-dimensional positioning

Low-cost inertial and barometric sensing offers an autonomous route to three-dimensional (3D) positioning when global navigation satellite system (GNSS) signals are unavailable or unreliable. In long-duration pedestrian dead reckoning, however, displacement error, heading drift, altitude drift, and local trajectory-sha...
