developed in australia, dme was invented by james "gerry" gerrand under the supervision of edward george "taffy" bowen while employed as chief of the division of radiophysics of the commonwealth scientific and industrial research organisation (csiro). another engineered version of the system was deployed by amalgamated wireless australasia limited in the early 1950s operating in the 200 mhz vhf band. this australian domestic version was referred to by the federal department of civil aviation as dme(d) (or dme domestic), and the later international version adopted by icao as dme(i).
