UNSPSC 25173133: Instrument landing system/distance measuring equipment system

Instrument Landing System/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 the time-lapse of a signal transmitted by the aircraft to the station and responded back. DMEs can also provide groundspeed and time-to-station readouts by differentiation.

UNSPSC 25173133 Instrument landing system/distance measuring equipment system is a Commodity code with minimal recent state and local procurement activity aligned to its nominal scope. The recent opportunities tagged under this code do not reflect purchases of instrument landing systems or distance measuring equipment; instead, they show state and local bodies procuring aircraft avionics repair services, thermal imaging camera installation, and unmanned aerial systems for specialized operations. Middle Georgia State University posted an eRFQ in February 2026 for FAA-certified avionics repair services supporting 53 aircraft and helicopters across its flight training program, and the State of Oregon Department of State Police issued an ITB in February 2026 for the one-time purchase and installation of a FLIR thermal imaging camera system on a Cessna T206H. These opportunities reflect state and local demand for aircraft systems integration and repair rather than navigational landing equipment specifically.

The issuing bodies tagged under this code include a state university aviation program and a state law enforcement agency, with geographic activity in Georgia and Oregon. The mismatch between the code's stated scope and the actual work being solicited suggests that either the code is underutilized for its intended purpose or that state and local procurement offices are applying it inconsistently to aircraft-related systems work more broadly. A business development professional evaluating this code should verify whether recent opportunities genuinely require instrument landing system or distance measuring equipment expertise before investing pursuit resources, or consider whether related aircraft systems and avionics work represents the actual procurement signal worth monitoring under this taxonomy.
