The collective name for a group of eight radio antennas, located at three observatories in New South Wales, Australia, owned and operated by the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The antennas can be used individually, or in various combinations as a long-baseline interferometer. The heart of the ATNF is the Compact Array at the Paul Wild Observatory, Narrabri, consisting of six dishes, 22 m in diameter, in a line 6 km long. The largest individual instrument is the 64-m dish at Parkes Observatory, 300 km to the south of the Compact Array. Between these two sites lies another 22-m dish at Mopra Observatory, near the town of Coonabarabran. The Australia Telescope began operation in 1988. Its headquarters are in Epping, NSW.
