University of Adelaide researchers in South Australia are developing the world's most precise clock which will be able to boost a key defence asset that safeguards Australia. The University?s Institute for Photonics and Advanced Sensing (IPAS) has been awarded a $2 million contract by the Australian Government to adapt and develop its Sapphire Clock which is the culmination of 15 years of investment in leading-edge fundamental research. It can now deliver signals that are more than 100 times more precise than any competing technology. Scientists developing the clock have been participating in the CSIRO ON Innovation Program https://www.adelaide.edu.au/news/news89202.html
