Distance Measuring Equipment ('''[[DME]]''') uses the same frequencies as a VOR. A DME tells the equipment on board of the aircraft the distance towards the transponder. It is two-way communication between the equipment on-board and the DME station to calculate the result.

While a VOR can be a stand-alone beacon, a DME will be paired with a VOR, a '''VOR-DME'''. Both senders will contain information about the other and tuning will be automatic. If the VOR station fails it defaults to a stand alone DME.
