The Giant Metrewave Radio Telescope consists of

The Giant Metrewave Radio Telescope (GMRT), located near Pune, India, is a world-class radio interferometer designed for low-frequency radio astronomy. It consists of an array of 30 fully steerable parabolic dish antennas, each with a diameter of 45 meters. These antennas are distributed in a specific 'Y' configuration, with 14 antennas located in a compact central square of approximately 1 km² and the remaining 16 spread along three arms extending up to 14 km. The GMRT operates as an aperture-synthesis array, allowing it to function as a single large telescope with a maximum baseline of about 25 km. This configuration enables high-resolution imaging of celestial objects at meter wavelengths, ranging from 150 MHz to 1.4 GHz.
