Indian Deep Space Network (IDSN)

Indian DSN (IDSN) facility is situated at Byalalu village near Bengaluru.  There are three antennas: 11 meter antenna, 18 meter antenna and 32 meter antenna. These are used for communication with deep space exploration spacecrafts.  The 18 m antenna was mainly built for Chandrayaan-1 mission. 32 m antenna is used for communication with probe like Mangalyaan.

Heart of the Indian Deep Space Network (IDSN), the monster antenna is the only link between Chandrayaan-1 spacecraft orbiting the Moon some 380,000 kilometers away and the team of ISRO scientists at the Spacecraft Control Centre (SCC) located at Peenya in Bangalore.

Chandrayaan-1 is continuously tracked by a worldwide network of ground stations belonging to ISTRAC and space agencies of USA, Russia and Brazil. Ground stations in this network are located in Bangalore, Trivandrum, Port Blair, Lucknow and Sriharikota in India; Mauritius, Brunei, Biak (Indonesia), Cuba, Alcantara (Brazil), and Bears Lake (Russia); and Maryland, Hawaii, and Goldstone (California) of USA.

The IDSN is the first of its kind in the country which provides ISRO the capability to handle deep space missions of India and also provide cross-support to similar missions of other space agencies because of its inter-operable features and world standard specifications and state-of-the-art capabilities.

The project was executed under the supervision of ISTRAC with the public sector Electronics Corporation of India as the prime contractor and participation six other companies including Godrej & Boyce, Larsen & Toubro, and Hindustan Aeronautics Limited. The ISRO Satellite Centre in Bangalore designed the radio frequency system and Bhabha Atomic Research Centre in Mumbai developed the antenna control servo system.
