Abstract
A method and system for localizing a mobile device includes deriving and using a spatial derivative magnetic signature or fingerprint. The method, executed in a processor of the mobile device, comprises monitoring mobile device magnetic data along a route being traversed, deriving, from the mobile device magnetic data, a mobile device spatial derivative magnetic fingerprint along the route, accessing a repository of spatial derivative magnetic fingerprint data having associated respective positions along the route, and localizing the mobile device based at least partly on matching the mobile device spatial derivative magnetic fingerprint with the spatial derivative magnetic fingerprint data of the repository.
