    摘要: 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.
