UK timing trial using eLoran
UK company Arqiva, which provides timing and frequency technology for broadcast, satellite and telecomms use, is to trial eLoran alongside GPS.
The communications infrastructure company is trialling eLoran timing technology - which delivers precise UTC traceable time - from the Anthorn transmitter in Cumbria.
Institute Corporate Member Chronos Technology is running the trial through a UK Innovate Agency grant under project 'GAUL'.
As a provider of broadcast, satellite and telecomms services, Arqiva relies on accurate time and frequency. So, by trialling the eLoran technology alongside its existing GPS facilities, 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 or space weather events.
Chronos Technology MD, Prof Charles Curry, commented: 'We are delighted to be working with Arqiva on this project to trial eLoran timing to complement existing GPS-derived time. The project will compare eLoran and GPS timing and their relative stability and accuracy to UTC. It will also demonstrate how eLoran timing signals can be continuously synchronised to UTC, using the Loran Data Channel, for indoor-only reception locations.'
Arqiva RF Technology Director, Simon Mason, added: 'We need precise time for our transmissions to ensure we deliver the best service that we can to our customers. During this trial we are aiming to achieve sub-microsecond accuracy relative to common time scales, such as UTC.'
