Abstract
Determining whether a mobile device is inside an environment experiencing adverse pressure variation conditions. Particular systems and methods for determining whether a mobile device is inside an environment experiencing adverse pressure variation conditions detect a change in pressure measured by a mobile device that is caused by an HVAC effect of a building or a vehicle, determine a likelihood that the mobile device is inside a building based on an estimated position of the mobile device relative to the building, and determine that the mobile device is inside the building or inside a vehicle based on the likelihood that the mobile device is inside the building.
