More Information
Summary:Disclosed are systems, methods and techniques for calibrating a barometric pressure sensor of a mobile device. In one embodiment, a barometric pressure sensor of a mobile device may be calibrated by determining that the mobile device has returned to a frequently visited location at which an altitude is known. The know altitude may then be used for calibrating the barometric pressure sensor for obtaining altitude measurements based on raw measurements obtained by the barometric pressure sensor.
