Abstract

Systems and methods to determine a location of a mobile device by combining a radio frequency navigation system and an inertial navigation system, where the radio frequency navigation system determines a location of the mobile device in reference to a map of radio frequency signals and the inertial navigation system based on dead reckoning the position of the mobile device based on measurements from motion sensors and/or magnetic field sensors. The mobile device combines the position determination results from the radio frequency navigation system and the inertial navigation system to determine two successive locations. A heading of the user of the mobile device is computed from the two successive locations without using the orientation of the mobile device.
