Abstract:
An example of a technique for maintaining a previously calibrated mobile device positioning system to account for changes in perturbers of the Earth's magnetic field. A mobile device obtains a corrected heading estimate of the mobile device within a space based on a previously recorded heading correction value. The mobile device also calculates a device heading relative to a previously orientated map of the space. The mobile device subsequently updates the heading correction value with any deviation between the corrected heading estimate and the calculated device heading.

Claim (Index 9):
A system, comprising:\n a server platform, comprising:\n a memory; \n a network interface; \n a processor coupled to the network interface and the memory; and \n server code stored in the memory; and \n a non-transitory tangible computer readable medium embodying client code for execution by a processor of a mobile device, wherein execution of the client code configures the mobile device to implement functions, including mobile device functions to:\n capture, via an image sensor of the mobile device, one or more images including at least one signal modulated within visible light, wherein:\n the visible light is transmitted from a plurality of visible light sources located within a space; \n any one signal is modulated within visible light transmitted by a respective one visible light source; and \n each modulated signal corresponds to a respective identity of a respective visible light source; \n \n process the one or more images to determine, based at least in part on the at least one modulated signal, an estimated location of the mobile device within the space; \n capture, via a compass of the mobile device, a raw heading measurement; \n obtain a corrected heading estimate based at least in part on the raw heading measurement; \n determine a likely orientation of the mobile device relative to a map of the space; \n compare the corrected heading estimate and the likely orientation of the mobile device relative to the map of the space to obtain an apparent deviation; and \n transmit, via a network interface of the mobile device and to the server platform, the apparent deviation and the estimated location of the mobile device; and \n wherein execution of the server code configures the server platform to implement functions, including server functions to:\n receive, from the mobile device, the apparent deviation and the estimated location of the mobile device; and \n update, based on the apparent deviation, a previously stored deviation angle.
