, operated by CSIRO. The name hails from the location of the facility close to Mopra Rock a geological formation overlooking the telescope. It is also close to the Siding Spring optical observatory in the Warrumbungle National Park.

For use as a single-dish, it has niche equipment allowing large bandwidths to be observed at millimeter-wavelengths. Being a part of the Australia Telescope, it is often used in conjunction with other AT antennas (e.g., the Australia Telescope Compact Array

Very Long Baseline Interferometry is a type of astronomical interferometry used in radio astronomy. It allows observations of an object that are made simultaneously by many telescopes to be combined, emulating a telescope with a size equal to the maximum separation between the telescopes.Data...

(VLBI) array.

Commissioned in 2006 was the Mopra Spectrometer (MOPS) "backend" which has a maximum instantaneous bandwidth of 8 GHz, it also has special zoom-modes which allow high resolution studies of up to 16 138 MHz bands over any 8 GHz. It is especially tuned to the high-performance millimeter-wavelength receivers. The main specialty of the instrument is the response of the 3-mm receiver which nominally can observe between 75-115 GHz. New downconversion equipment fine-tuned the 3-mm system while it also received a 12-mm receiver package early-2006.

Until 2006, the telescope was operated on-site by visiting users. The default mode shifted to remote operation from the ATCA, Narrabri in the winter of 2006.
