Simultaneous Localization and Calibration (SLAC) Methods for a Train-Mounted Magnetometer
Navigation, 2023 Magnetic field localization is based on the fact that the Earth’s magnetic field is distorted in the vicinity of ferromagnetic objects. When ferromagnetic objects are in fixed positions, the distortions are also fixed and, thus, contain location ...

Accurate Covariance Estimation for Pose Data From Iterative Closest Point Algorithm
Navigation, 2023 One of the fundamental problems of robotics and navigation is the estimation of the relative pose of an external object with respect to the observer. A common method for computing the relative pose is the iterative closest point (ICP) algorithm, where a ...
