Opportunistic calibration of a barometer in a mobile device

Disclosed are systems, methods and techniques for calibrating an altimeter of a mobile device. For example, a characterized motion of a mobile device may be used to infer an altitude of the mobile device. If it is further inferred that the mobile device is in an outdoor environment, an altitude of t...

Summary:Disclosed are systems, methods and techniques for calibrating an altimeter of a mobile device. For example, a characterized motion of a mobile device may be used to infer an altitude of the mobile device. If it is further inferred that the mobile device is in an outdoor environment, an altitude of the mobile device may be based on application of an estimated location of the mobile device to an altitude terrain map.
