Two receivers located within a region of interest that is sufficiently small as compared to a distance to a source of a signal can be considered a 'point'. Signals received at that “point” are planar. Accordingly, any difference in the time of arrival of a signal from the source by one receiver as compared to another receiver located within that region stablishes a locus of points representing a distance between the receivers perpendicular to the vector pointing to the source. Using signals from multiple far sources multiple loci on which one receiver must exist as compared to the other receiver can be identified. The convergence of these loci identifies a relative position of one receiver from the other, and when the geospatial position of one receiver is known, so too is the position of the other receiver.
