Arqiva, the communications infrastructure company, is trialling eLoran timing technology – which delivers precise UTC traceable time – from the Anthorn transmitter in Cumbria. Chronos Technology is running the trial through its Innovate UK – the UK’s Innovation Agency – grant supported research project “GAUL”.


As a provider of broadcast, satellite and telecommunications services, Arqiva is dependent on accurate time and frequency, so by trialling the eLoran technology alongside its existing Global Positioning System (GPS), it will be able to monitor any time and frequency inaccuracies that can occur as a result of external factors, such as local interference, jamming, spoofing and space weather events.
