Abstract: Disclosed are methods, systems, devices, apparatus, computer-/processor-readable media, and other implementations, including a method that includes obtaining, at a mobile device, remote transmitter location estimates for one or more remote transmitters, obtaining, at the mobile device, a group of pedestrian dead-reckoning (PDR) measurements, obtaining, at the mobile device, a group of signal measurements for signals received from the one or more remote transmitters, and deriving at least one mobile device location estimate for the mobile device based on one or more inconsistency terms representative of inconsistency between different location solutions, for the at least one mobile device location estimate, computed using different data points from the remote transmitter location estimates for the one or more remote transmitters, the group of PDR measurements, and the group of signal measurements.
