Systems and methods for determining a barometric pressure bias of a mobile device

A device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, to:
• determine that a trigger condition is satisfied;
• determine, based on the trigger condition being satisfied, a geographic location of the device;
• receive an altitude value that identifies an altitude for the geographic location of the device;
• receive a measured barometric pressure value that identifies a measured barometric pressure for the geographic location;
• determine an expected barometric pressure for the geographic location of the device based on a reference altitude, a reference barometric pressure, and the altitude for the geographic location of the device,
• wherein the reference altitude and the reference barometric pressure are associated with a reference location;
• receive one or more other measured barometric pressure values that identify one or more other measured barometric pressures for one or more other geographic locations of the device;
• determine one or more other expected barometric pressures for the one or more other geographic locations of the device, based on the reference altitude, one or more other reference barometric pressures that are associated with the reference location, and altitudes for the one or more other geographic locations of the device
• wherein the expected barometric pressure and the one or more other expected barometric pressures are a set of expected barometric pressures, and
• wherein the measured barometric pressure and the one or more other measured barometric pressures are a set of measured barometric pressures;
• determine that the device has reached a destination location;
• determine, based on determining that the device has reached the destination location, a barometric pressure bias that is based on respective differences between at least a subset of the set of expected barometric pressures and a corresponding subset of the set of measured barometric pressures;
• and
• perform one or more actions based on the barometric pressure bias.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
• determine that a trigger condition is satisfied;
• determine, based on determining that the trigger condition is satisfied, a set of geographic locations of the device,
• wherein the set of geographic locations are determined periodically;
• receive a set of altitude values that identify a set of altitudes that correspond to the set of geographic locations;
• determine a set of measured barometric pressures that correspond to the set of geographic locations;
• determine a set of expected barometric pressures that correspond to the set of geographic locations,
• wherein the set of expected barometric pressures are determined based on a reference altitude associated with a reference location, a set of reference barometric pressures associated with the reference location, and the set of altitudes that correspond to the set of geographic locations,
• determine a barometric pressure bias that is based on respective differences between at least a subset of the set of expected barometric pressures and a corresponding subset of the set of measured barometric pressures;
• and
• perform one or more actions based on the barometric pressure bias.
