UNSPSC 25173132: Doppler VHF omnidirectional range distance measuring system

Doppler VHF Omnidirectional Range (DVOR)/DME (Distance Measuring Equipment) is an international, standardized navigation system. DME allows an aircraft to automatically measure its physical line of sight distance (in nautical miles) from a selected ground-based beacon. DME systems are used throughout the world by all airliners.

UNSPSC 25173132 Doppler VHF omnidirectional range distance measuring system (Commodity) covers aircraft surveillance and navigation transmitter equipment that state and local governments procure for airport operations and law enforcement aviation missions. Recent solicitations show the code capturing ground-based and airborne transmitter systems—specifically Vehicle Movement Area Transmitters (VMATs) equipped with Automatic Dependent Surveillance-Broadcast (ADS-B) technology for surface awareness and traffic management. State and local buyers issuing under this code include airport commissions managing ground-vehicle surveillance infrastructure and state law enforcement and environmental agencies operating aviation fleets. The Savannah Airport Commission has been the repeat issuer in the available recent activity, soliciting turnkey VMAT installation, integration, and commissioning work as the dominant procurement pattern.

The Savannah Airport Commission posted two related RFQs (RFQ 2026-0037 and RFQ20260037, due October 15, 2026) requesting quotations for furnishing, installing, configuring, and integrating forty Vehicle Movement Area Transmitters (thirty-eight operational units and two spares) on airport-owned vehicles, with scope spanning equipment supply, installation labor, FAA registration and coordination, testing, training, and one-year warranty. Both solicitations require FAA Buy American Preference compliance, bidder experience with at least three comparable airport projects within five years, and offer City of Savannah Local Small Business and Minority Business designations. Delivery is to 640 Gulfstream Road, Savannah, Georgia 31408, with evaluation projected October 16–November 30, 2026 and award notification by December 1, 2026. A separate RFP from the Texas Department of Public Safety (405-26R0027111, due September 24, 2026) for Cessna 208 Caravan completion upgrades with law enforcement avionics includes aircraft surveillance and communication systems but does not focus on the transmitter systems that define this commodity code. The New Jersey Department of the Treasury posted an aircraft maintenance and parts contract (26DPP01247, due October 9, 2026) serving the State Police Aviation Bureau and Department of Environmental Protection but centers on repair services and parts supply rather than transmitter procurement. Activity under this code concentrates in Georgia and shows sparse recent state and local solicitation volume.
