Abstract:
Systems and methods to determine a location of a mobile device based on a radio frequency navigation system and an inertial navigation system, where the radio frequency navigation system is used to determine a location of the mobile device in reference to a map of radio frequency signals and the inertial navigation system is based on dead reckoning the position of the mobile device based on measurements from motion sensors and/or magnetic field sensors. The position determination results from the radio frequency navigation system and the inertial navigation system are combined to determine two successive locations. A heading of the user of the mobile device is computed based on weighted averages for the two successive locations.

Claim (Index 1):
A method to determine a location of a mobile device, the method comprising:\n storing a map of radio frequency signal characteristics in a region identified in the map; receiving, from a transceiver of the mobile device, radio frequency signals in the region emitted from a plurality of beacons located in a transport corridor within the region; determining characteristics of the radio frequency signals received from the transceiver; matching the characteristics of the radio frequency signals with the frequency signal characteristics of the map to determine two successive first locations; receiving, via sensors of the mobile device, motion data, including orientation data and acceleration data of the mobile device; computing two successive second locations from the motion data; determining a confidence level of the two successive first locations and a confidence level of the two successive second locations; determining two successive third locations of the mobile device, the determining being based at least on computed weighted averages of the two successive first locations and the two successive second locations, the computed weighted averages being based on the confidence levels of the two successive first locations and the two successive second locations; and computing a heading of a user of the mobile device based on the two successive third locations of the mobile device.
