Systems and methods for determining a barometric pressure bias of a mobile device

Abstract:

A device determines, periodically over time, geographic locations of the device. The device receives altitude values that identify altitudes for the geographic locations. The device determines measured barometric pressures for the geographic locations. The device determines expected barometric pressures for the geographic locations based on a reference altitude associated with a reference location, reference barometric pressures associated with the reference location, and the altitudes for the geographic locations. The device determines a barometric pressure bias that is based on respective differences between at least a subset of the expected barometric pressures and a corresponding subset of the measured barometric pressures for the geographic locations. The device performs one or more actions based on the barometric pressure bias.
