About Tracking Facility

ISRO Telemetry, Tracking and Command Network (ISTRAC) provide mission support to low-earth orbit satellites as well as launch vehicle missions. ISTRAC has its headquarters and a multi-mission spaceship Control Centre at Bangalore. It has a network of ground stations at Bangalore, Luck now, Sriharikota, Port Blair and Thiruvananthapuram in India besides stations at Mauritius, Bearslake (Russia), Brunei and Biak (Indonesia).

ISTRAC activities are organized into network operations, network augmentation, mission operation and spacecraft health monitoring, communications and computers and control centre facilities and development projects. Programme planning and reliability groups support ISTRAC activities.

The Indian Deep Space Network (IDSN), commissioned during the year 2008, at Byalalu village near Bangalore forms the Ground segment for providing deep space support for India’s prestigious and first Lunar mission, the Chandrayaan-1.The technical facilities in IDSN include a 32 meter Deep Space Antenna, an 18 meter Antenna Terminal, an 11 meter Antenna Terminal, Indian Space Science Data Centre (ISSDC) and a Technical Services complex.

The IDSN is the first of its kind project in the country that provides ISRO the capability to handle deep space missions of India and also provides cross support to other deep space missions of exterior space agencies because of its inter-operable features and state-of-the-art capabilities.

About Launching Facility

SDSC SHAR has the necessary infrastructure for launching satellite into low earth orbit, polar orbit and geostationary transfer orbit. The launch complexes provide entire support for vehicle assembly, fuelling, checkout and launch operations. Apart from these, it has facilities for launching sounding rockets meant for studying the earth’s atmosphere.

First Launch Pad:

The individual stages of PSLV or GSLV, their subsystems and the spacecraft are ready and checked out in separate facilities before they are sent to launch pad for integration A-76-meter tall mobile service tower (MST) facilitates the vertical integration of the vehicle.

The foldable working platforms of MST provide access to the vehicle at various elevations. An enormous launch pedestal, made up of steel plates, acts as the base on which the vehicle is integrated.

The spacecraft is integrated to the vehicle in a clean room, set up inside the MST. However, in the case of GSLV, the spacecraft is interfaced with the payload adopter and then encapsulated in the heat shield in the preparation facility itself.

The encapsulated assembly is moved to the launch pad for integrating with the 3rd stage of GSLV. The umbilical tower houses the feed lines for liquid propellants and high-pressure gases, checkout cables, and frozen air duct for supplying cool air to the satellite and equipment bay.
