Introduction
The Network consist of a fully steerable 18 m and a 32 m DSN antenna which improves the visibility duration when compared with the existing ISRO Telemetry Tracking and Command Network (ISTRAC). The established Indian Deep Space Network implements a base band 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 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 meter antenna has provision 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.
The 32-m antenna is of a wheel-and-track design. The antenna is designed to provide uplink in both S-Band and X-Band (20 kW) either through RCP or LCP. The reception capability will be in both S-Band and X-Band (simultaneous RCP and LCP). It can receive two carriers in S-Band and two carriers in X-Band. The system will have a G/T of 37.5/51 dB/k (45° elevation, clear sky) for S/X Band. The station is also equipped to control remotely from the ISTRAC Network Control Centre (NCC).
IDSN also houses the ISRO Navigation Centre (INC). It was launched on 28 May 2013 by V. Narayanasamy. The centre will become active on 12 June 2013, at the time of launch of IRNSS-1, the first of the Indian Regional Navigational Satellite System series of satellites. The INC has a high stability atomic clock. It will be used to co-ordinate across 21 ground stations in India.

Famous quotes containing the word introduction:
“We used chamber-pots a good deal.... My mother ... loved to repeat: “When did the queen reign over China?” This whimsical and harmless scatological pun was my first introduction to the wonderful world of verbal transformations, and also a first perception that a joke need not be funny to give pleasure.”
—Angela Carter (1940–1992)
“Do you suppose I could buy back my introduction to you?”

“For better or worse, stepparenting is self-conscious parenting. You’re damned if you do, and damned if you don’t.”
