Detailed explanation-3: -GMRT is an array of thirty fully steerable parabolic radio telescopes of 45 metre diameter. It is operated by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research. GMRT is an indigenous project.

Detailed explanation-4: -The GMRT will detect radio waves mainly with a wavelength of one metre from bodies such as quasars and pulsars. But it is also capable of operating at six different wavelengths from about 20 cm to as much as 8 metres – a range never studied before, says Swarup.
