Abstract
A method for calibrating a frequency receiver device (FRD) includes obtaining an image of a visually unique object having a visually unique pattern, the visually unique object disposed at a known location; detecting a match by comparing the pattern to a list of pre-determined patterns; upon detecting a match, determining a relative location of the FRD from the pattern based on the pattern and a new broadcast frequency of a frequency originator device (FOD) from a lookup table correlating a plurality of patterns, their corresponding known locations and a broadcast frequency of at least one corresponding FOD for each of the plurality of patterns and determining the location of the FRD from the FOD based on the relative location of the FRD from the known location of the pattern; and synchronizing a clock of a FRD and a clock of a FOD based on said new frequency of the FOD.
