Distance Measuring Equipment
|Term||Distance Measuring Equipment|
Ultra High Frequency (UHF) ground equipment that is used in conjunction with airborne equipment to determine distance between the airborne and ground equipment.
DME Distance is defined as the line of sight distance (slant range) from the source of a DME signal to the receiving antenna. DME operates on the interrogation-answer principle where the time required for the round trip of the signal exchange is measured in the airborne DME unit and translated into DME Distance.
