Limitation of barometric pressure sensor calibration by sporadic data acquisition

摘要

PROBLEM TO BE SOLVED: To calibrate a barometric pressure sensor of a mobile device. A plurality of calibration results for calibrating a barometric pressure sensor are determined based on data received from a device including the sensor and stored in a table. This table is updated based on the rules regarding the relationship between each calibration result and the current calibration value. The calibration results are weighted and combined to determine the combined calibration results. The calibration value for calibrating the sensor is selected from the calibration result, the combined calibration result, or the current calibration value based on the selection criteria.
