Pilots utilize the Distance Measuring Equipment (DME), a radio navigation tool, to calculate their aircraft’s slant range from a ground station.
The ground-based DME reacts with a response pulse signal after receiving a pulse signal from the DME avionics in an aircraft.
Radio navigation technology known as distance measuring equipment (DME) uses timing to determine the propagation delay of radio signals in the frequency range between 960 and 1215 megahertz to determine the slant range (distance) between an aircraft and a base station (MHz).
The global aircraft distance measuring equipment market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The Federal Aviation Administration (FAA) has recently awarded a contract to Selex ES Inc., a subsidiary of Leonardo that develops surveillance, en route navigation, and precision approach and landing systems, to continue developing distance measuring equipment in the United States (DME).
The agreement features two one-year option periods in addition to a one-year base period. Selex ES anticipates supplying the National Airspace System with more than 200 DMEs in addition to the prior FAA Selex ES DME contract .
Program management, systems engineering, design, development, testing, system assessment, training, manufacturing, Interim Contractor Depot Logistics Support (ICDLS), and site implementation are all included in the contract’s scope.
The DME system will provide a contemporary system that adheres with current FAA security standards, assisting the FAA in raising the operational availability and performance of the NAS.
Selex ES is the leading provider of DMEs in the world, having supplied more than 1200 DME systems to important clients in 25 years.
The Scottsdale, Arizona-based producer of test and monitoring equipment, Viavi Solutions, unveiled its brand-new AVX-10K flight line test set. The AVX-10K can report and transfer testing results and data through USB, Ethernet, and wireless, is compatible with Android and iOS devices, and features a digital touchscreen interface.
Very high frequency (VHF) radios, devices for measuring distances, and ADS-B Out transponders are just a few of the communications, navigation, and surveillance systems that can be tested with the AVX-10K. The DME 500, a fifth-generation piece of distance measurement equipment (DME) from Thales that is compatible with current onboard receivers, is about to make its debut.
An unmanned air system calibration flight is compatible with the DME 500. For the purposes of parameter checking and health monitoring, it can transmit enough data. Calibration can also be done immediately. The DME 500’s maintainability features include enhanced dependability, a smaller line of replacement modules, and a 20–30% reduction in power usage. It can live in the same shelter as a more aged DME.
At Raja Bhoj Airport, two new Doppler Very High-Frequency Omni Range (DVOR) and Distance Measuring Equipment (DME) were put into service as part of an improvement. With the new method, flights will always arrive safely and on time, even in challenging weather.
An aircraft’s position and heading in relation to its destination are determined with the use of the short- to medium-range radio navigation system known as DVOR. The slant rate between an aircraft and a ground station is measured using radio navigation technology called DME. When both are utilised together, the angle and slant distance of the aircraft with respect to the ground station are determined.
The outdated GCLE DVOR 755 and GCLE DME 753 system that was in place at the airport in Bhopal has been removed from service since it has reached the end of its useful life. Both the new DVOR equipment (South Korean), the model MOPIENS MARU 220 and HPDME equipment (Canadian), and the model: INTELCAN SKYNAV N9040 are state-of-the-art devices with cutting-edge technology that offer more precise and improved en-route guidance to aircraft for more than 200NM, or roughly 370 km.
The Bhopal airport handles both domestic and international traffic, and DVOR and DME are essential to the routing of both international and domestic flights since they transmit angle and distance information to in-flight aircraft. Here, the pilot can precisely pinpoint its location.
The ground-based DME receives a pulse signal from the DME avionics in an aircraft and responds with an answer pulse signal. The receiver in the aircraft determines the slant range distance by measuring the interval between the sent and received pulses.
Inertial navigation system (INS) measurements of location, velocity, and wind are updated using data from the aircraft distance-measuring equipment (DME). DME has been documented in numerous research datasets and is trustworthy and extremely accurate.
The DME’s main drawback is that it can only be used for land-based navigation. Pilots rely less on DME due to the emergence of the global positioning system (GPS). DME might be required, though, when they fly at great altitudes. Additionally, businesses are releasing new items with greater precision, which is anticipated to market growth.
