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.
