38-element radio telescope interferometer working in the frequency range of 1.2–6.0 GHz. The final baseline will be 2.27 km in the East-West and 1.17 km in the South directions, respectively. This instrument will obtain radio images from the sun with a spatial resolution ≈4x6 arc seconds.
These ten radio antennas work together as an array that forms the longest system in the world that uses very long baseline interferometry. The longest baseline available in this interferometer is about 8,611 kilometers (5,351 mi). [2] The construction of the VLBA began in February 1986 and it was completed in May 1993.
The VLA comprises twenty-eight 25-meter radio telescopes (twenty-seven of which are operational while one is always rotating through maintenance) deployed in a Y-shaped array and all the equipment, instrumentation, and computing power to function as an interferometer.
The Northern Extended Millimeter Array (NOEMA) is one of the largest astronomical facilities on European ground and the most powerful radio telescope in the Northern Hemisphere operating at millimeter wavelengths. It consists of a large array of twelve 15-meter antennas that can spread over distances of up to 1.7 kilometers, working together as ...
The radio interferometer continued to be expanded with larger and better radio telescopes. In 1979, the two dishes were retired from the radio interferometer and were repurposed to be used as an array dedicated to solar observation. The Owens Valley Solar Array was established with the two dish interferometer under the direction of professor ...
The Arcminute Microkelvin Imager (AMI) consists of a pair of interferometric radio telescopes - the Small and Large Arrays - located at the Mullard Radio Astronomy Observatory near Cambridge. AMI was designed, built and is operated by the Cavendish Astrophysics Group .
The Green Bank Observatory (previously National Radio Astronomy Observatory, Green Bank) is an astronomical observatory located in the National Radio Quiet Zone in Green Bank, West Virginia, U.S. It is the operator of the Robert C. Byrd Green Bank Telescope , the world's largest fully steerable radio telescope .
The Robert C. Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia, US is the world's largest fully steerable radio telescope, [1] surpassing the Effelsberg 100-m Radio Telescope in Germany. [2] The Green Bank site was part of the National Radio Astronomy Observatory (NRAO) until September 30, 2016.
