Abstract
A method and system of magnetic parameter based mobile device localization. The method comprises receiving, from a mobile device under traversal along an indoor path within an indoor area, a series of magnetic parameter measurements at each of a plurality of path segments; identifying, based on accessing reference magnetic data associated with the indoor path, an initial match for respective ones of a subset of path segments in accordance with the magnetic parameter measurements; initializing a set of alternative trajectories of the mobile device in accordance with the initial match; and determining, from the set of alternative trajectories, a current trajectory of the mobile device based at least in part on a best fit with a number of path segments associated with set of alternative trajectories.
