Indian Space Research Organisation Telemetry, Tracking and Command Network

The Indian Space Research Organization (ISRO), over the years, established a comprehensive network of ground stations to provide Telemetry, Tracking and Command (TTC) support to satellite and launch vehicle missions. These facilities are grouped under ISRO Telemetry, Tracking and Command Network (ISTRAC) with its headquarters at Bangalore, India.

Facilities

• ISTRAC facilities in Bangalore consists of, TTC ground station (BLR) with full redundancy Multi-mission Spacecraft Control Center to carryout and control spacecraft operations and co-ordinate with the network stations. Computer facility with distributed architecture providing independent processors for communications handling, dedicated processors to provide real-time displays for individual spacecraft missions and off-line processors for carrying out spacecraft data archival, analysis and orbit determination.

• Communication Control facility to establish links between SCC and ISTRAC network stations as well as control centers of other participating external space agencies and data receptions stations through dedicated voice, data and TTY links.

• Limited TTC facility to provide on orbit operational support to INSAT satellites as back up to INSAT Master Control Facility at Hassan.

Mission

Tracking, Commanding and House Keeping data acquisition as well as health analysis and control, orbit and attitude determination and network co-ordination support to all Low Earth orbit satellite missions of ISRO throughout their mission life.

Telemetry data acquisition support for ISRO launch vehicle missions from lift off till satellite acquisition and down range tracking support for monitoring and determining the satellite injection parameters.

Providing the close co-ordination between spacecraft and launch vehicle teams, supporting ground stations right from planning till the completion of mission for the national and international satellite missions.

Telemetry, Tracking and command support for the International satellite launch projects.
