Air Traffic Control & Navigation Aids installations at King Khalid International Airport (RUH)

Air Traffic Control & Navigation Aids covers the systems that manage airspace and the ground infrastructure that guides aircraft to the runway: ATC tower consoles and voice-communication systems, primary and secondary surveillance radar, wide-area multilateration and space-based ADS-B, A-SMGCS surface management, and the navigation aids themselves — instrument landing systems, VOR/DME, frangible navaid structures and approach lighting interfaces. Buyers are air navigation service providers, civil aviation authorities and airport operators. Procurement is governed by ICAO Annex 10, EUROCONTROL and the local CAA, with long certification and integration cycles. The GCC's ANSPs and fast-growing greenfield airfields are continuously upgrading surveillance and digital-tower capability, making this a standing procurement line distinct from terminal IT.

A sprawling 1980s-era masterplan set in desert pink sandstone, RUH was designed by HOK when Riyadh was still a secondary capital. Four decades later, the city has outgrown it. Terminals 1, 2, 3, 4 and 5 now share the load as traffic hit 37.2 million in 2024, and new carrier Riyadh Air prepares to launch before the airport itself is eclipsed by King Salman International just across town.
