Abstract
Systems and methods for estimating a height of a mobile device are described. A reference pressure estimate is generated using atmospheric data from one or more reference locations. Various approaches for determining the reference pressure estimate are described. The reference pressure estimate is used, along with a pressure measurement at a position of a mobile device, to estimate the height of the mobile device.
