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.

Far-source position determination

A system and method for evaluating the interactivity of RF devices in a virtual RF environment having selective virtual spectrum users remotely controlled by a web browser, where the virtual spectrum users have selectable interactivity parameters, and the virtual RF spectrum can be selectively changed, and the performance of the virtual spectrum users is evaluated and assigned scores as a function of the evaluation to determine which virtual spectrum user receives the highest amount of points.
