Aviation & Air Traffic Control

Airport and air-traffic-control operations run on one common time: UTC. Voice recording, radar tracks, flight data and logging must all sit on the same traceable time, because a time difference between systems makes incident reconstruction unreliable.

What we typically roll out in aviation:

• GMR5000 or GMR6000 as a multi-GNSS-disciplined grandmaster with NTP and PTP, and time-code output (IRIG-B) where older systems require it
• Redundant configuration: two independent time sources with their own antennas, plus a holdover oscillator (OCXO or Rubidium) in case GNSS drops out
• NTP100-GNSS as a stratum-1 source for ground and office networks
• NTDS clocks in operational rooms with UTC display; DA12 to distribute reference signals to several systems

Points to note for aviation:

• Traceability to UTC is the core: the time source must be demonstrably traceable to UTC
• Anti-jamming: a ground signal is vulnerable; multi-GNSS plus a good holdover oscillator bridges interference or loss
• Antenna installation with lightning and surge protection is not an option but a requirement on an airport roof

We do not supply radar, communication or flight-data systems — that is the domain of specialised ATC vendors. The traceable time reference beneath them is our expertise.
