A team of Australian scientists, including researchers from The Australian National University (ANU), have found a new way to use the telecommunications network to synchronise radio telescopes, which help scientists peer into deep space.
Linking radio telescopes in an array currently requires that each telescope has access to an atomic clock to record the precise time when a signal is detected from an object in space.
Co-lead researcher Professor Ken Baldwin from ANU said the team demonstrated for the first time that a stable frequency reference can be reliably transmitted more than 300 kilometres over the fibre optic network to link two radio telescopes. ...
