UNSPSC 25173135: Differential global positioning system - ground station

The underlying premise of differential GPS (DGPS) requires that a GPS receiver, known as the base station, be set up on a precisely known location. The base station receiver calculates its position based on satellite signals and compares this location to the known location.

UNSPSC 25173135 Differential global positioning system - ground station (Commodity) covers Vehicle Movement Area Transmitters and related aviation surveillance ground infrastructure that state and local transportation authorities procure for airport operations and law enforcement aviation. The Savannah Airport Commission is the primary recent buyer, soliciting forty VMATs under RFQ 2026-0037 (due October 15, 2026) for installation, configuration, and integration on airport-owned vehicles within the Airport Movement Area. The scope is a complete turnkey solution: furnishing brand-new equipment, performing installation and FAA registration, testing and commissioning, training, and providing minimum one-year warranty coverage. Equipment must be FAA-compliant, operate on 978 MHz UAT frequency, and integrate with the FAA Surface Awareness Initiative (SAI) environment using ADS-B technology. The solicitation requires firm-fixed pricing itemized across seven components (VMAT equipment, installation, registration, testing, training, optional warranty, and optional maintenance) and compliance with FAA Buy American Preference under 49 U.S.C. Section 50101 unless a waiver is granted. Bidders must demonstrate successful completion of at least three comparable airport projects within the previous five years and must hold FAA Part 145 repair station certification or equivalent aviation maintenance credentials. The Savannah Airport Commission offers Local Small Business and Minority Business designations; LSBE qualification requires physical location within Savannah city limits and a current City of Savannah Business Tax Certificate. Evaluation is projected October 16–November 30, 2026, with award notification expected by December 1.

The recent opportunity activity under this code is concentrated in Georgia, with the Savannah Airport Commission accounting for both identified RFQs (appearing as dual entries for the same procurement under different tracking numbers). A secondary opportunity from the Texas Department of Public Safety (RFP 405-26R0027111, due September 24, 2026) involves completion upgrades to a Cessna 208 Caravan EX law enforcement aircraft and includes avionics and mission-system integration that tangentially touches ground surveillance and communications infrastructure, though the primary scope is aircraft-based rather than ground-station equipment. A third opportunity from the New Jersey Department of the Treasury (Bid Solicitation 26DPP01247, due October 9, 2026) covers maintenance and repair services across a fleet of 21 aircraft operated by the State Police Aviation Bureau and Forest Fire Service, with labor-rate components but no ground-station procurement. The code shows limited recent activity; the Savannah VMAT procurement is the clearest match to the commodity's nominal scope, while secondary opportunities signal broader state and local aviation infrastructure modernization but do not center on differential-GPS ground stations or related positioning equipment.
