Giant Meterwave Radio Telescope consists of

The Giant Metrewave Radio Telescope (GMRT), located near Pune in Maharashtra and operated by the National Centre for Radio Astrophysics (NCRA-TIFR), is one of the world's largest radio telescopes operating at metre wavelengths. It consists of 30 fully steerable parabolic dish antennas, each 45 metres in diameter, arranged in a Y-shaped configuration spread over about 25 km. It uses the principle of aperture synthesis to combine signals from all the dishes. Hence it consists of multiple parabolic antennas.
