A method in accordance with an aspect of the present disclosure includes receiving a first ranging signal from an asset tag. The method also includes receiving a second ranging signal that was transmitted a known delay after the first ranging signal. The second ranging signal is from another device. Such a method further includes computing a pseudo-range between a point of reception and the asset tag based at least in part on a time difference between the first ranging signal and the second ranging signal. |
