The high sensitivity of the feed system in the Ooty Radio Telescope, located in southern India, has allowed it to be used for the studies of astrophysical phenomena, and as of 2017, the ORT is undergoing a major upgrade to its receiver chain.
As of 2017, the ORT is undergoing a major upgrade to its receiver chain, which will result in a new system called the Ooty Wide Field Array (OWFA). The high sensitivity of the feed system and the large collecting area of ORT has been exploited for the studies of astrophysical phenomena such as pulsars, solar wind, recombination lines, and protogalaxies. The Ooty Radio Telescope (ORT) is located in Muthorai near Ooty, in southern India.
