Systems and methods for pressure sensor calibration

摘要

Systems and methods are disclosed for calibrating a pressure sensor associated with a mobile device. Location information may be determined for the mobile device and used to obtain reference pressure information. The reference pressure information may then be used to calibrate the pressure sensor. Additionally, when the pressure sensor of the mobile device has been calibrated, output from the pressure sensor may be used as reference pressure information by another device.

1. A method for calibrating a pressure sensor associated with a mobile device comprising:
determining location information for the mobile device; receiving reference pressure information from an external source based at least in part on the determined location information; measuring pressure with the pressure sensor; and calibrating the pressure sensor using the measured pressure and the reference pressure information; wherein the reference pressure information and the measured pressure correspond to different time periods.
