In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ground station is required.

Distance Measuring Equipment (DME) is a measuring device using ground and air components to determine the slant range of an aircraft from a point; DME equipment functions by using paired radio signals between the aircraft and ground stations

Distance Measuring Equipment (DME) is is a short/medium range navigation system, which operates of the principle of a secondary radar system that enables an aircraft to establish its range from a ground station.

2017年12月1日 · Distance measuring equipment (DME) is a system requiring both aircraft-installed and ground-based equipment, with the latter normally co-located with a VHF omnidirectional radio range (VOR) or, sometimes, an instrument landing system (ILS).

2024年3月18日 · DME is used for measuring the slant range between the aircraft and facility. It operates in the 960 – 1215 MHz band. The DME avionics in aircraft sends a pulse signal to the ground based DME, which responds with an answer pulse signal.

2021年11月9日 · Distance measuring equipment (DME) requires both ground-based and in-aircraft equipment. You'll usually find DME equipment co-located with a VOR or ILS/LOC. NAVAIDs like VORs and ILS systems transmit their navigation signals over VHF.

2022年6月7日 · Distance Measuring Equipment (DME) is an analog navigational system that employs UHF and VHF radio frequencies to determine your distance to a location in space.

A DME measures your line-of-sight / slant range distance to the VOR station, a figure that is influenced by your altitude. A GPS measures the distance between your current latitude / longitude coordinates and those of your waypoint.

Distance Measuring Equipment (DME) is defined as a combination of ground and airborne equipment which gives a continuous slant range distance-from-station readout by measuring time-lapse of a signal transmitted by the aircraft to the station and responded back.

2024年6月26日 · Distance Measurement Equipment (DME) is a transponder-based radio navigation system that measures slant range distance by timing the propagation delay of radio signals. The DME system is composed of a transmitter/receiver (interrogator) in the aircraft and a receiver/transmitter (transponder) on the ground.
