Australia Telescope Compact Array

(radio telescope in eastern Australia)

The Australia Telescope Compact Array (ATCA) is a radio telescope in New South Wales, Australia operated by the CSIRO (Commonwealth Scientific and Industrial Research Organisation) at the Paul Wild Observatory. It consists of six 22 meter dishes with baseline up to 6 km, with receivers for frequencies ranging from 1.1 GHz to 105 GHz, which should allow angular resolutions down to about 0.1 arcsecond (i.e., with ideal configuration, resolution direction, and wavelength). They are also used for very-long-baseline interferometry with other Australian radio telescopes. It has been in operation since 1988.
