  "textContent": "A method and system of magnetic parameter based mobile device localization. The method comprises obtaining a predetermined number of magnetic parameter measurements corresponding to a plurality of path segments in an indoor path traversed by a mobile device. Based on accessing a reference database associated with the indoor path, a set of reference segments having a magnetic parameter measurement matching a first magnetic parameter measurement may be identified. In accordance with the identified set of reference segments, a set of alternative trajectories of the mobile device are identified. From the set of alternative trajectories, a current alternative trajectory of the mobile device with a maximum match to the first magnetic parameter measurement may be determined. The current alternative trajectory may be iteratively extended to determine a final alternative trajectory matching the predetermined number of magnetic parameter measurements, the mobile device being localized in accordance with the final alternative trajectory.",
