US 2013/0095848 A1 · METHOD AND SYSTEM FOR INDOOR RF MAPPING

Abstract

A method is disclosed for determining a location of a mobile electronic device. The mobile electronic device receives an RF signal providing RF fingerprint data and receives a third party location estimate from a third party service. Location data is collected by a dead reckoning system and corresponds to RF fingerprint data and third party estimates collected for a plurality of locations. A correlation between the RF fingerprint data, the third party location estimates, and location data is determined providing a transform for transforming the third party location estimates into a more accurate location estimate of the mobile electronic device.

Dependent claims

A method comprising:

providing RF fingerprint data related to each of a plurality of locations wherein the plurality of locations comprises a first location;
at each of the plurality of locations:
receiving from a third party third party location estimate data based on sensed signals;
sensing location data indicative of a geographical location;
processing the RF fingerprint data, the third party location estimate data, and the location data to determine correlation data comprising a first transform for transforming the third party location estimate data to determine second location estimate data;
and
storing the third party location estimate data and the correlation data for each of the plurality of locations.
