 Well, maybe. The computer simulation is only accurate to about a football field size as far as location is concerned. The apparent accuracy is greater than the actual accuracy. It's still trial-and-error, because there will be hot spots and cold spots at a location when the signals are diffracted by terrain obstacles.
