DME and operation
DME was largely identical to Gee-H in operation, but used new electronics to automatically measure the time delay and display it as a number, rather than having the operator time the signals manually on an oscilloscope.
It ran the VME operating systems, and supported emulation of both the earlier architectures ( 1900 Series and System 4 ), either standalone ( DME, Direct Machine Environment ) or concurrently with native-mode operation ( CME, Concurrent Machine Environment ).
DME and will

DME and navigation
Common uses for VHF are FM radio broadcasting, television broadcasting, land mobile stations ( emergency, business, private use and military ), long range data communication with radio modems, amateur radio, marine communications, air traffic control communications and air navigation systems ( e. g. VOR, DME & ILS ).

* Air traffic equipment such as navigation aids ( DVOR, DME, ILS and GP )
Distance measuring equipment ( DME ) is a transponder-based radio navigation technology that measures slant range distance by timing the propagation delay of VHF or UHF radio signals.

DME and navigational
This usage is important in situations where other navigational equipment, such as VORs with distance measuring equipment ( DME ), have failed.
A terminal DME, referred to as a TDME in navigational charts, is a DME that is designed to provide a 0 reading at the threshold point of the runway, regardless of the physical location of the equipment.

DME and systems
These are essentially DME systems located in space.
By this time the LORAN-C and Decca Navigator systems were dominant in the medium-range roles, and short-range was well served by VOR and DME. The expense of the clocks, lack of need, and the limited accuracy of a long wave system eliminated the need for such a system for many roles.
These ran the VME and DME ( emulation ) operating systems, and were available in both single and multi-processor configurations, the later being known as Duals and SuperDuals ( 2966 and 2988 only ).
Land-based systems such as VOR and DME, because they operate " line of sight ", are mostly useless for ocean crossings, except in initial and final legs within about of those facilities.
Direct Machine Environment, abbreviated DME, was a mainframe environment for the ICL 2900 Series of computing systems from International Computers Limited that was developed in the 1970s.
DME was more-or-less an ICL 1900 order code processor in microcode, which permitted the ICL 1900 series executive, operating systems and program libraries to operate on the ICL 2900 series.
DME and such

Dimethyl ether ( DME ) is also gaining popularity as a refrigerant.
This led to the possibility that DME interrogation pulses from different aircraft might be confused, but this was solved by having each aircraft send out a different series of pulses which the ground-based transponder repeated back.
DME is almost always used in conjunction with VOR, and is normally co-located at a VOR station.
This combination allows a single VOR / DME station to provide both angle and distance, and thereby provide a single-station fix.

In modern ILS installations, a DME is installed, co-located with the ILS, to augment or replace marker beacons.
A DME continuously displays the aircraft's distance to the runway.
Distance measuring equipment ( DME ) provides pilots with a slant range measurement of distance to the runway in nautical miles.
The DME provides more accurate and continuous monitoring of correct progress on the ILS glideslope to the pilot, and does not require an installation outside the airport boundary.
When used in conjunction with an ILS, the DME is often sited midway between the reciprocal runway thresholds with the internal delay modified so that one unit can provide distance information to either runway threshold.
