Claim 17:
18. The method of claim 16, wherein the pressure pattern includes a set of isobars, and wherein determining if the expected reference-level pressure is within the threshold amount of pressure comprises:
determining if the estimated position of the mobile device and one or more locations of one or more reference pressure sensors in the network of reference pressure sensors are located on or between a pair of isobars of the set of isobars that are separated by no more than the threshold amount of pressure; and
if the estimated position of the mobile device and the one or more locations of one or more reference pressure sensors in the network of reference pressure sensors are located on or between the pair of isobars, determining that the expected reference-level pressure is within the threshold amount of pressure from a reference-level pressure of a reference pressure sensor of the one or more reference pressure sensors, wherein that reference pressure sensor of the one or more reference pressure sensors is the selected reference pressure sensor.
