Ooty Radio Telescope
From Wikipedia, the free encyclopedia
The Ooty Radio Telescope near Ootacamund (Ooty) was set up by TIFR radio astronomers, in the picturesque Nilgiri Hills of South India in 1970. Designed and built in India, the Ooty Radio Telescope (ORT) is an off-axis parabolic cylinder 530 m long and 30 m wide operating at a nominal frequency of 326.5 MHz with a maximum bandwidth of 15 MHz at the front-end. The reflecting surface of the telescope is made of 1100 thin stainless-steel wires running parallel to each other for the entire length of the cylinder and supported on 24 steerable parabolic frames. An array of 1056 half-wave dipoles in front of a 90 degrees corner reflector forms the primary feed of the radio telescope.
