The UK's main air navigation service provider, an early remote/digital tower operator.
NATS is the United Kingdom's principal air navigation service provider. It operates the remote digital tower for London City Airport from its Swanwick centre using Saab r-TWR, making London City the first major international airport fully controlled by a remote digital tower. NATS is also a partner on Hamad International's Virtual Tower (vTWR) in Doha with Searidge and ADB Safegate, in operational service since February 2025 and announced November 2025 as the first large-scale digital tower certified by a Middle East regulator (QCAA). NATS and NAV CANADA are widely reported as joint owners of Searidge Technologies, though that ownership was not re-verified against a primary source in this pass (unverified). As an ANSP, NATS runs the air traffic service itself, which distinguishes it from the associations, regulators, and vendors in this space.
