1. A method for determining a geo-location of an object, the method comprising:
- comparing a plurality of ambient atmospheric pressure measurements obtained for an object against a gridded atmospheric model; and
based at least in part on the comparison, determining a geo-location of the object.

Abstract
System and method for geo-location of a device (such as a tag) using barometric pressure readings taken in the vicinity of the device and correlated to datasets of barometric pressure that have pressure gradients over time and space. The readings taken in the vicinity of the device may be correlated to the datasets using an iterative Bayesian approach to determine a geo-location of the device with a high degree of confidence.
