UNSPSC 25202911: Multilateration surveillance

Multilateration Surveillance (MLAT) is an airborne or ground system used for monitoring the positions of aircraft and other objects for the purpose of air traffic management.

UNSPSC 25202911 Multilateration surveillance, a Commodity code, covers detection and tracking systems that use signal triangulation and time-difference-of-arrival methods to locate aircraft and other targets without requiring transponder cooperation. State and local governments procure this technology primarily through airport authorities, aviation departments, and regional air-traffic management bodies to enhance airfield safety, detect non-cooperative or low-visibility aircraft, and support emergency response operations. The systems integrate with existing air-traffic control infrastructure and often support both civilian and emergency-services use cases, including search-and-rescue coordination and airspace security monitoring.

No recent state and local contract opportunities appear in the available records for this code. The lack of recent solicitation activity suggests either infrequent procurement cycles typical of specialized aviation infrastructure, narrow vendor qualification requirements, or reliance on cooperative purchasing vehicles and sole-source awards that may not generate public notice activity. Business development professionals should monitor aviation authority RFPs and state transportation agency initiatives for capital equipment cycles and upgrades to air-traffic control systems, as multilateration surveillance deployments typically occur on multi-year or multi-phase schedules tied to facility modernization efforts rather than recurring annual buys.
