The Indian Deep Space Network (IDSN) is a network of large antennas and communication facilities that supports the interplanetary spacecraft missions of India. It 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 antenna was designed and commissioned by Hyderabad-based Electronics Corporation of India Limited at a cost of Rs 62 crore to Rs 65 crore (about 13 million US dollars).[1]
Other similar networks include ESTRACK of the European Space Agency, the Deep Space Network of the United States NASA, the Soviet Deep Space Network, and the Chinese Deep Space Network.
Introduction
The network consists of a fully steerable 18 metres (59 ft) and a 32 metres (105 ft) DSN antenna which improves the visibility duration when compared with the existing ISRO Telemetry Tracking and Command Network (ISTRAC). 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 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 m 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.[clarification needed] It has a G/T of 30/39.5 dB/k (45° elevation, clear sky) for S/X-Band.[clarification needed]
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 may be controlled remotely from the ISTRAC Network Control Centre (NCC).[where?]
The IDSN facility in Byalalu 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.[2][needs update]
Antennas
32 m antenna
The first 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.[citation needed] 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 RCP or 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).[3]
18 m antenna
The second antenna is an 18-meter Deep Space Antenna. A fibre optic / satellite link will provide[needs update] the necessary communication link between the IDSN Station and Mission Operations Complex (MOX) / Indian Space Science Data Centre (ISSDC). This antenna is capable of S-Band uplink (2 kW) and both X-Band and S-Band downlink. This system has provision to receive two downlink carriers in S-Band and one carrier in X-Band (RCP and LCP) simultaneously, whereas, the uplink is either RCP or LCP.[clarification needed] The system will have a G/T of 30/39.5 dB/K (45° elevation, clear sky) for S/X-Band.[clarification needed] The base-band system will adhere to the CCSDS Standards. The station can be remotely operated from ISTRAC Network Control Centre (NCC).[citation needed]
11 m antenna
The third antenna is an 11-meter terminal[clarification needed] antenna which was built for the ASTROSAT Mission. It started tracking satellites in July, 2009.[citation needed]
Chandrayaan-1
The Indian Deep Space Network has been built to track and support India's first lunar mission Chandrayaan-1, an unmanned lunar exploration mission by the Indian Space Research Organisation (ISRO), India's national space agency. 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 was 2 years though 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 satellite separated from the launch vehicle.
Mars Orbiter Mission
IDSN is being used to track the Mars Orbiter Mission (MOM) also known as Mangalyaan. The launch window available is for about 20 days starting 28 October 2013.[4]
