Science & Technology
Giant Metrewave Radio Telescope (GMRT)
Consider the following statements:
- Giant Metrewave Radio Telescope (GMRT) consists of 30 fully steerable gigantic parabolic dishes of 45m diameter each, spread over distances of up to 25 km.
- The metre wavelength part of the radio spectrum has been particularly chosen for study with GMRT because man-made radio interference is considerably lower in this part of the spectrum in India.
- GMRT is located in Hyderabad.
