Abstract

A method and system of localizing a mobile device having a processor and a memory. The method comprises localizing the mobile device to a first set of positions along a route traversed in the indoor area using a full set of data fusion inputs that includes at least wireless signal data, inertial sensor data, and magnetic field data based on one or more sensor devices of the mobile device, receiving an indication of a magnetic field distortion along the route being traversed, contemporaneous with the localizing to the first set of positions based on the full set of data fusion inputs, localizing the mobile device to a second set of positions along the route based on a subset of the set of data fusion inputs that does not include the magnetic data, and when the first and second sets of positions coincide in accordance with a threshold difference in distance, reverting to localizing the mobile device in accordance with the full set of data fusion inputs.
