Giant Metrewave Radio Telescope is the world's most sensitive low-frequency radio interferometer and it is in the final stage of the upgrade. One of the key objectives of this upgrade is to improve sensitivity along with obtaining near seamless frequency coverage from 100 to 1500 MHz. As a part of this upgrade, new wideband feeds and digital backend with 400 MHz bandwidth capability have been put in place.
