The ISRO '''Telemetry, Tracking and Command Network (''ISTRAC'')''' is one of the ground segment arms of Indian Space Research Organisation and was established on September 06, 1976. It consists of a comprehensive global network of ground stations to provide telemetry, tracking and command (TTC) support to [[satellite]] and [[launch vehicle]] missions. <ref>{{Cite web |title=ISTRAC inaugurates Golden Jubilee Celebrations: 50 Years of Tracking India's Space Odyssey |url=https://www.isro.gov.in/ISTRAC_inaugurates_Golden_Jubilee_Celebrations.html |access-date=2025-09-10 |website=www.isro.gov.in}}</ref>

==Facilities==
ISTRAC has several facilities as of November 2013:{{citation needed|date=December 2013}}
* ISTRAC facilities in Bangalore consist of TTC ground station (BLR) with full redundancy multi-mission Spacecraft Control Center to carry out 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 [[Spacecraft Control Centre|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.

==Mission==
The mission of the ISTRAC includes:{{citation needed|date=December 2013}}
*Tracking, commanding and housekeeping 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 liftoff until satellite acquisition and down range tracking support for monitoring and determining the satellite injection parameters.
*Coordinating 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.

==Ground Stations==
ISTRAC has the following TTC ground stations:<ref name=irso17j>{{cite web |title=Indian Deep Space Network (IDSN) |url=http://www.isro.org/chandrayaan/htmls/ground_segment_spacenetwork.htm |publisher=ISRO |access-date=17 January 2013 |archive-url=https://web.archive.org/web/20131022161359/http://isro.org/chandrayaan/htmls/ground_segment_spacenetwork.htm |archive-date=22 October 2013 |url-status=dead }}</ref>
