Status of Activities and Plans for Precise Time Comparisons in Australia

Abstract

The routine use of artificial satellites has revolutionized precise time comparisons in Australia in this decade. Global Positioning System (GPS) time transfer units are operating in Sydney, Melbourne, Canberra, Alice Springs and Yaragadee (Western Australia) and provide the major link between the atomic clocks in those centers. They also provide the Link with international time scales on a daily basis, superseding the clock trips from the USA every three months or less frequently. A project is being developed to use TV transmissions the Australian domestic satellite AUSSAT for comparisons over a large part of the country to replace the terrestrial TV system which is no longer useable for this purpose.
