Abstract
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 a location of the mobile device is on a particular discrete vertical of a plurality of discrete vertical levels.
Claims30
A method, at a mobile device, comprising:
- determining that the mobile device is located at a frequently visited location and that an onboard barometric pressure sensor is in a calibrated state;
- determining that the mobile device is located on a particular discrete vertical level of a plurality of discrete vertical levels at the frequently visited location;
- determining an altitude value based, at least in part, one or more signals from the onboard barometric pressure sensor;
- and
- storing the determined altitude value in association with the particular discrete vertical level, the frequently visited location, or both.

A mobile device comprising:
- an onboard barometric pressure sensor;
- a memory device;
- and
- a processing unit configured to:
- determine that the mobile device is located at a frequently visited location and that the onboard barometric pressure sensor is in a calibrated state;
- determine that the mobile device is located on a particular discrete vertical level of a plurality of discrete vertical levels at the frequently visited location;
- determine an altitude value based, at least in part, one or more signals from the onboard barometric pressure sensor;
- and
- store the determined altitude value in the memory device in association with the particular discrete vertical level, the frequently visited location, or both.

A method at a mobile device comprising:
- determining that the mobile device is located on a discrete vertical level at a frequently visited location;
- obtaining one or more barometric pressure measurements from an onboard barometric pressure sensor;
- selecting a discrete level from among a plurality of discrete vertical levels identified in a memory device based at least in part on the obtained one or more barometric pressure measurements;
- and
- aligning the obtained one or more barometric pressure measurements with an altitude value stored in the memory device corresponding to the selected discrete vertical level to calibrate the onboard barometric pressure sensor.
