Indian Deep Space Network

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 which improves the visibility duration when compared with the existing ISTRAC system. The Indian Deep Space Network implements a baseband system{{clarify|date=December 2013}} adhering to Consultative Committee for Space Data Systems (CCSDS) Standards, thus facilitating cross-support among the Telemetry Tracking Command (TTC) agencies.{{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}}

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.{{clarify|date=December 2013}}

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 has a measured G/T of 37.3/49.1 dB/k in the S/X bands.{{cite journal |title=Two Stage Gain Magnification in Beam Wave Guide Feed of Indian Deep Space Network (IDSN-32) Station

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.{{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 |date=29 May 2013 |access-date=1 June 2013 |location=Jaduguda, India}}{{update after|2013|12|1}}

The main antenna is a 32-meter Deep Space Antenna. The wheel and track antenna, built in a beam waveguide configuration, is a state-of-the-art system that supported the Chandrayaan-1 and later the Mars Orbiter Mission mission operations.{{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}} It is currently supporting the Chandrayaan-2 orbiter and the Aditya-L1 mission as well as actively tracking the Chandrayaan-3 Propulsion module. 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 or Left circular polarization. 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).{{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 }}

{{main|Chandrayaan-1}}

The Indian Deep Space Network was built to track and support India's first lunar mission Chandrayaan-1, an uncrewed 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.

{{main|Mars Orbiter Mission}}

IDSN had been used to track Mars Orbiter Mission (MOM) also known as Mangalyaan.{{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 }}

The IDSN32 antenna will be used for science data collection from the Venus Orbiter Mission Spacecraft, planned to be launched in 2028.{{Cite web |title=Union Cabinet Approves India's Mission to Venus, and Sample Return from the Moon |url=https://www.isro.gov.in/UnionCabinetApprovesIndiasMission.html |access-date=2024-10-03 |website=www.isro.gov.in}}
