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.

[1] It was built under the leadership of S K Shivakumar, the then ISTRAC Director and inaugurated on 17 October 2008 by the former ISRO chairman G. Madhavan Nair.

Similar networks are run by USA, China, Russia, Europe, and Japan.

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[clarification needed] adhering to Consultative Committee for Space Data Systems (CCSDS) Standards, thus facilitating cross-support among the Telemetry Tracking Command (TTC) agencies.

The antenna is designed to provide uplink in both S-Band and X-Band (20 kW) either through RCP or LCP.

The base-band will adhere to CCSDS Standards facilitating cross-support among the space agencies.
