'''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 spaceflight|interplanetary]] [[spacecraft]] missions of India. Its hub is located at [[Byalalu]], [[Ramanagara district|Ramanagar]] in the state of [[Karnataka]] in India.<ref>{{Cite web |url=https://www.isro.gov.in/indian-space-science-data-centre-issdc-gateway-to-indias-space-science-data |title=Indian Space Science Data Centre (ISSDC) - Gateway to India's Space Science Data - ISRO |access-date=3 December 2019 |archive-date=1 September 2019 |archive-url=https://web.archive.org/web/20190901140723/https://www.isro.gov.in/indian-space-science-data-centre-issdc-gateway-to-indias-space-science-data |url-status=dead }}</ref> It was inaugurated on 17 October 2008 by the former [[ISRO]] chairman [[G. Madhavan Nair]].

Similar networks are run by [[NASA Deep Space Network|USA]], [[Chinese Deep Space Network|China]], [[Soviet Deep Space Network|Russia]], [[ESTRACK|Europe]], and [[Japanese Deep Space Network|Japan]].

==Introduction==

The network consists of the [[ISRO Telemetry, Tracking and Command Network]] (ISTRAC), augmented by a fully steerable {{convert|18|m|ft|abbr=on}} and a {{convert|32|m|ft|abbr=on}} DSN [[Antenna (radio)|antenna]] which improves the visibility duration when compared with the existing ISTRAC system. The Indian Deep Space Network implements a [[baseband]] system{{clarify}} adhering to [[Consultative Committee for Space Data Systems]] (CCSDS) Standards, thus facilitating cross-support among the Telemetry Tracking Command (TTC) agencies.<ref>{{cite web |url=http://www.vssc.gov.in/VSSC_V4/index.php/ground-segment/82-chandrayaan-1/967-indian-deep-space-network-idsn |title=Welcome to VIKRAM SARABHAI SPACE CENTRE - Indian Deep Space Network (IDSN) |website=www.vssc.gov.in |url-status=dead |archive-url=https://web.archive.org/web/20151020022026/http://www.vssc.gov.in/VSSC_V4/index.php/ground-segment/82-chandrayaan-1/967-indian-deep-space-network-idsn |archive-date=2015-10-20}} </ref>

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]] ([[Right circular polarization|RCP]] and [[Left circular polarization|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.{{clarify}}

The 32 m antenna is of a wheel-and-track design. The antenna is designed to provide uplink in both [[S band|S-Band]] and [[X band|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 may be controlled remotely from the ISTRAC Control Centre (NCC) at Bangalore.

The IDSN facility in [[Byalalu]] also houses the ISRO Navigation Centre (INC). The centre became active on 12 June 2013, at the time of launch of [[IRNSS-1A]], the first of the [[Indian Regional Navigation 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]].<ref>{{cite news |url=http://www.thehindu.com/todays-paper/tp-national/isro-unveils-hub-for-its-navigation-fleet/article4761288.ece |title=ISRO unveils hub for its navigation fleet |work=[[The Hindu]] |access-date=1 June 2013 |location=Jaduguda, India}}</ref>{{update after|2013|12|1}}

==Antennas (other than ISTRAC)==

===32 m antenna===

The main antenna is a 32-meter Deep Space Antenna. The wheel and track 32 m antenna is a state-of-the-art system that supported the [[Chandrayaan-1]] mission operations. It is currently supporting [[Mars Orbiter Mission]]<ref>{{cite web |title=Mangalyaan successfully placed into Mars Transfer Trajectory |url=http://news.biharprabha.com/2013/12/mangalyaan-successfully-placed-into-mars-transfer-trajectory/ |access-date=1 December 2013}}</ref> This is co-located with 18 m antenna in the IDSN site at [[Byalalu]]. A fibre optics / satellite link will provide the necessary connectivity between the IDSN site and Spacecraft Control Centre / Network Control Centre. This antenna is designed to provide uplink in both S-Band (20/2 kW) and X-Band (2.5 kW), either through [[Right circular polarization|RCP]] or [[Left circular polarization|LCP]]. The reception capability will be in both S-Band and X-Band (simultaneous RCP & LCP). It can receive two carriers in S-Band and one carrier in X-Band, simultaneously. The system will have a [[G/T]] of 37.5/51 dB/K (45° elevation, clear sky) for S/X-Band. The base-band will adhere to [[CCSDS]] Standards facilitating cross-support among the space agencies. The station is also equipped for remote control from the ISTRAC Network Control Centre (NCC).<ref>{{Cite web |url=http://isro.org/chandrayaan/htmls/ground_segment_spacenetwork.htm |title=Indian Deep Space Network (IDSN) - Website |access-date=27 October 2008 |archive-date=5 November 2014 |archive-url=https://web.archive.org/web/20141105203059/http://www.isro.org/Chandrayaan/htmls/ground_segment_spacenetwork.htm |url-status=dead }}</ref>

==Chandrayaan-1==
{{main|Chandrayaan-1}}

The Indian Deep Space Network was built to track and support India's first lunar mission [[Chandrayaan-1]], an unmanned [[Exploration of the Moon|lunar exploration]] mission. It was launched on 22 October 2008. The IDSN was used for tracking, orbit control and housekeeping operations of India's lunar mission for its entire duration of operation (Planned to be 2 years, achieved only 312 days). IDSN began to track Chandrayaan 17 minutes after its launch from the Satish Dhawan Space Launch Centre at [[Sriharikota]], when the probe separated from the launch vehicle.

==Mars Orbiter Mission==
{{main|Mars Orbiter Mission}}

IDSN had been used to track Mars Orbiter Mission (MOM) also known as [[Mangalyaan]].<ref>{{Cite web |url=http://www.isro.org/mars/updates.aspx |title=ISRO - Mars updates |access-date=12 July 2014 |archive-date=3 December 2013 |archive-url=https://web.archive.org/web/20131203010404/http://isro.org/mars/updates.aspx |url-status=dead }}</ref>
