Established in 1976, ISRO Telemetry, Tracking and Command Network (ISTRAC) plays the vital role of tracking and communicating with all the satellite and launch vehicle missions of the Indian Space Research Organization (ISRO). ISTRAC has a network of TTC ground stations at Bengaluru, Lucknow, Sriharikota, Thiruvananthapuram, and Port Blair in India and in Brunei, Biak (Indonesia) and Mauritius. ISTRAC also maintains the Indian Deep Space Network (IDSN) for space science and exploration missions.

Indian Deep Space Network (IDSN)

The IDSN Campus is located in the village of Byalalu near the city of Bengaluru, Karnataka state of India. IDSN consists of three large antennas for supporting communications with space science and planetary exploration missions of the Indian Space Research Organization (ISRO).

  • 32 meter antenna (S/C – Band)
  • 18 meter antenna (S – Band)
  • 11 meter antenna (S/X – Band)

Mission Operations Complex (MOX)

MOX is part of the ISRO Telemetry, Tracking and Command Network (ISTRAC) to perform all mission operations related to remote-sensing, science and exploration missions of the Indian Space Research organization (ISRO). MOX has facilities such as the Main Control Room, the Mission Analysis Room, Mission Planning and Flight Dynamics, the Mission Scheduling and Payload Scheduling Facility. All network stations of ISTRAC are connected to MOX through dedicated high-performance satellite/terrestrial communication links. ISRO has established MOX-1 (2008) and MOX-2 (2010) in a separate campus to support dual launch missions simultaneously.

Indian Space Science Data Center (ISSDC)

ISSDC is a facility established by ISRO as the primary data center for the payload data archives of Indian Space Science and Exploration Missions. The data center, located in the Indian Deep Space Network (IDSN) campus is responsible for the ingestion, archive, and dissemination of the payload data and related ancillary data for these missions. ISSDC interfaces with Mission Operations Complex (MOX) through dedicated communication links, Data reception centers, Payload designers, Payload operations centers, Principal investigators, Mission software developers and Science data users. ISRO Science Data Archive (ISDA) is the repository of all the science data from the Indian space science and exploration missions. ISDA has adopted the Planetary Data System (PDS) standards. ISRO is a member of the International Planetary Data Alliance.

ISRO Navigation Center (INC)

The ISRO Navigation Center (INC) located at the Indian Deep Space Network (IDSN) Complex at Byalalu, near Bengaluru is the primary ground segment for the independent Indian Regional Navigation Satellite System (IRNSS). The INC is responsible for providing the time reference, generation of navigation messages and monitoring and control of ground facilities including ranging stations of IRNSS. It hosts several key technical facilities for supporting various navigation functions. The high precision timing facility at INC is equipped with high stability, high precision atomic clocks to provide stable and continuous time reference to the navigation system.

The state of the art data processing and storage facilities at INC enable swift processing of data and support its systematic storage. INC is connected to the geographically distributed ranging stations across India and to the satellite control facilities through two highly reliable dedicated communication networks consisting of satellite and terrestrial links. The hub for the satellite communication links is hosted at ISRO Navigation Center (INC).

ISRO Space Situational Awareness (SSA) Control Center

Recognizing the need for dedicated efforts to tackle the growing challenge of operating in the crowded and contested space domain, ISRO has established the Directorate of Space Situational Awareness and Management (DSSAM) for improved operational mechanisms to protect Indian space assets through effective coordination amongst ISRO/DOS Centres, other space agencies and international bodies, and establishment of necessary supporting infrastructures. NEtwork for space object TRacking and Analysis (NETRA) project has been initiated as a first step, its main elements being a radar, an optical telescope facility, and a control center. On 14 December 2020, the ISRO SSA Control Center was inagurated in the ISTRAC Campus at Peenya, Bengaluru.
