Segmentation Analysis

The Airport Navaids – Global Market is segmented by Type and Application. Types include systems such as Instrument Landing System (ILS), Distance Measuring Equipment (DME), VHF Omnidirectional Beacon (VOR), and Others (e.g., NDB, localizers, marker beacons, visual aids). In terms of application, the market segments into Civil Airports and Military Airports. Each type and application sees different adoption rates depending on airport size, traffic volume, and regulatory environment. Civil airports — commercial and general aviation — represent the bulk of demand due to higher traffic and regulatory pressure. Military airports also contribute demand, especially for navigation reliability and redundancy. This segmentation allows stakeholders to tailor strategies depending on the type of aid and the end-use environment.

By Type

• Instrument Landing System (ILS): Globally, about 1,500 ILS installations remain operational at airports worldwide, underscoring the continued relevance of ILS for precision approaches under low-visibility conditions. ILS provides both lateral (localizer) and vertical (glideslope) guidance, enabling safe landings at night or in adverse weather, down to decision heights as low as zero for CAT III configurations. In many existing airports — especially international and major civil aerodromes — ILS remains mandatory for scheduled commercial operations, ensuring global consistency and safety.
• Distance Measuring Equipment (DME): DME is widely used to determine the slant range (distance) between aircraft and ground stations, complementing other Navaids. In response to satellite outages or GNSS vulnerabilities, several navigation authorities have added over 123 new DME stations in the 2024–2026 cycle to support RNAV (DME-DME) navigation and redundancy. Airports using DME enhance situational awareness for pilots and air traffic controllers, enabling better approach and departure procedures even when satellite signals are compromised.
• VHF Omnidirectional Beacon (VOR): VOR has historically been a primary means of radio navigation for commercial and general aviation. At the turn of the millennium, there were about 3,000 VOR stations worldwide, including 1,033 in the U.S. However, as satellite-based navigation gained dominance, the number of VORs has decreased: by 2013, the U.S. had reduced VOR stations to 967. Under current modernization programs, many VORs are being decommissioned or retained only as part of a Minimum Operational Network (MON) to provide backup during GPS outages.
• Others (NDB, Localizer, Marker Beacons, Visual Aids): Other Navaids such as Non-Directional Beacons (NDB), localizers, marker beacons, and visual landing/lighting aids also contribute, especially at smaller airports or where legacy infrastructure remains. While global reliance on these older aids has declined, some regional and remote airports continue to use them due to lower installation and maintenance costs, or due to lack of satellite infrastructure. Their presence ensures broader geographic coverage and support for general aviation, remote operations, or smaller aerodromes that may not justify high-end systems.

By Application

• Civil Airport: Civil airports — encompassing commercial airlines, general aviation, regional and international airports — constitute the largest share of demand in the Airport Navaids – Global Market. The high volume of passenger traffic, stringent safety regulations, and schedule reliability requirements necessitate precision landing systems, DME coverage, and backup Navaids. Most scheduled commercial airports maintain ILS (CAT I/II/III) or equivalent precision approach systems, supported by DME or VOR for backup navigation, especially in regions with GNSS vulnerabilities.
• Military Airport: Military airports also represent a significant segment of the market. Such airports often require robust, redundant navigation systems that are independent of satellite-based navigation, especially in conflict zones or remote areas. Military operations may rely on a combination of ILS, DME, VOR (or TACAN), and other Navaids to ensure operational readiness under all conditions, including GPS jamming or denial. As such, military airports continue to maintain and modernize ground-based Navaids systems, contributing to consistent demand in this application segment.
