Abstract
Techniques for calibrating a barometer sensor of a user equipment over time are discussed herein. In some cases, the accuracy of the barometer sensor may degrade over time. Techniques can include determining that the UE is at a consistent location over time. When the UE is at the location, the sensor data can be captured over time and stored. Data can be grouped by time periods (e.g., weekly, monthly, etc.) and a metric, such as an average value, can be determined. Over time, metrics can be compared to determine a drift in sensor accuracy. Differences in metrics can be used to determine calibration data, such as an offset, to calibrate subsequent sensor data. The offset can be applied to later-captured sensor data to provide more accurate data, which can ultimately result in more a more accurate determination of an elevation of the UE.
