The Automatrics MTrack wireless tracker device has an inbuilt Radio Distress Beacon. This can be detected by hand held radio receivers operating at one of 1000 secret radio frequencies. We collate the approximate location of the tracker using Cell Triangulation, then we home in on the radio beacon to an accuracy of less than one metre.
