The Department of Transportation, specifically the Federal Aviation Administration (FAA), has announced a single-source procurement opportunity for the replacement of the Maintenance Display Unit (MDU) associated with the Airport Surveillance Radar 9 (ASR-9) Sustainment 3 Project. This procurement involves the acquisition of custom Mobile Carts from VSGI SolutionZ Inc., which are essential for processing video signals from the ASR-9 system, as the current equipment has become obsolete and lacks supportability. The FAA emphasizes that ADB Safegate is the only approved manufacturer for the necessary control equipment, which is designed to interface with existing lighting systems. For further inquiries, interested parties can contact Haylee Hildebrand at haylee.p.hildebrand@faa.gov.
