Sapphire Clock’s JORNey

Andre LuitenMartin O’ConnorFred Baynes and Waddah Al-Ashwal, members of the Sapphire Clock team, recently visited the Jindalee Operational Radar Network (JORN) near Laverton, WA. The JORN site is part of the Australian Airforce’s monitoring and surveillance, covering between 1000-3000km of local and international airspace.  

The Sapphire Clock is a cryogenic sapphire oscillator that allows time to be measured to the femtosecond scale (one quadrillionth of a second), with only a single second gained or lost every 40 million years. This kind of accuracy is required for ultra high precision measurements; such as radar technology used at JORN.
