Features
The large size of the telescope makes it highly sensitive. As an example, it is in principle capable of detecting signals from a mere 1 watt radio station located 10 million km away in space. The telescope sits on a natural slope of 11°, which matches the latitude of the location. This gives the telescope an equatorial mount which allows tracking of celestial sources for up to ten hours in the east-west direction. In the north-south direction, the telescope operates as a phased-array and is steerable by varying the phase gradients
The telescope can be operated in either total power or correlation mode. In each mode, 12 beams are formed and Beam 1 is the southern most beam and Beam 12 is the northern most. These 12-beam systems are useful in sky-survey type of observations. Recently, the reflecting surface of the ORT has been refurbished. A new digital back-end has been built for the ORT by the colleagues at Raman Research Institute (RRI), Bangalore.

Famous quotes containing the word features:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
