Indian Deep Space Network (IDSN) is a network of large antennas and communication facilities operated by the Indian Space Research Organisation to support the interplanetary spacecraft missions of India. Its hub is located at Byalalu, a village about 40 kilometres (25 mi) from Bangalore, India. It was inaugurated on 17 October 2008 by the former ISRO chairman G. Madhavan Nair. The main tracking antenna was designed and commissioned by Hyderabad-based Electronics Corporation of India Limited at a cost of ₹620 to 650 million (about US$13 million).
The network consists of the ISRO Telemetry, Tracking and Command Network (ISTRAC), augmented by a fully steerable 18 m (59 ft) and a 32 m (105 ft) DSN antenna which improves the visibility duration when compared with the existing ISTRAC system. The Indian Deep Space Network implements a baseband system adhering to Consultative Committee for Space Data Systems (CCSDS) Standards, thus facilitating cross-support among the Telemetry Tracking Command (TTC) agencies.
The two antennas at the Byalalu complex have built-in support facilities. A fibre optic link will provide necessary communication link between the DSN station and SCC/NCC/ISSDC. The 18 m antenna is provisioned to receive two downlink carriers in S band and two carriers in X band (RCP and LCP), whereas the uplink is either RCP or LCP. It has a G/T of 30/39.5 dB/k (45° elevation, clear sky) for S/X-Band.
