The Australia Telescope Compact Array (ATCA) is a radio telescope operated by CSIRO at the Paul Wild Observatory, twenty five kilometres (16 mi) west of the town of Narrabri in Australia.

The telescope is an array of six identical 22-metre (72 ft) diameter dishes, which commonly operate in aperture synthesis mode to produce radio images. Five of the dishes can be moved along a three-kilometre (2 mi) railway track. The sixth antenna is situated three kilometres west of the end of the main track. Each dish weighs about 270 tonnes (270 long tons; 300 short tons).

The Compact Array is a part of the Australia Telescope National Facility network of radio telescopes. The array is frequently operated together with other CSIRO telescopes, the sixty-four-metre (210 ft) dish at the Parkes Observatory and a single 22-m dish at Mopra (near Coonabarabran), to form a very long baseline interferometry array.

In Fiction[edit]

The children's/young adult drama Sky Trackers was filmed in this facility in 1994 with the radio telescopes being prominently featured.
