Approach Navigation Systems offers the full range of airport approach aids, including Non-Directional Beacons (NDB), Distance Measuring Equipment (DME), Instrument Landing Systems (ILS), and VHF Omnidirectional Range (VOR). ANS Inc. provides quality products including those of Nautel, Selex, and others, which meet the standards of ICAO, FAA and Transport Canada.
Any conventional navigation aid can be supplied, installed, and maintained, at very competitive prices.
ILS (Instrument Landing Systems)
An instrument landing system (ILS) is a ground-based instrument approach system that provides precision guidance to an aircraft approaching and landing on a runway. Using a combination of radio signals and in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorological conditions (IMC), such as low ceilings or reduced visibility due to fog, rain, or blowing snow.
DME (Distance Measuring Equipment)
Distance Measuring Equipment (DME) provides pilots with a slant range measurement of distance to the runway in nautical miles. DME’s provide more accurate, continuous monitoring of correct progress during precision approaches. DME’s are also used in conjunction with NDB’s for non precision approach procedures. DME’s are also employed on board vessels and oil rigs for helicopter operations.
NDB (Non-Directional Beacons)
A Non-Directional Beacon (NDB) is a radio transmitter at a known location, used as an aviation or marine navigational aid. As the name implies, the signal transmitted does not include inherent directional information, in contrast to other navigational aids such as low frequency radio range, VHF omnidirectional range (VOR) and TACAN. NDB signals follow the curvature of the earth, so they can be received at much greater distances at lower altitudes, a major advantage over VOR.
To complement the navaids, ANS can provide the related instrument approach procedures, as well as GPS procedures to any runway or point-in-space. Flight inspection and chart production to the latest standards can be included in a turn-key service.
