By operationalizing and certifying components of the communication and ground support network, including systems connected to Amazon Web Services (AWS), ISRO has made a major advancement in its preparations for the Gaganyaan mission.
By supporting the SpaDeX (Space Docking Experiment) mission, the space agency verified that the AWS network was successfully tested and validatedIn addition, ISRO conducted a series of Radio Frequency Compatibility Tests to verify network operations with the European Space Agency (ESA) ground station.

The ESA ground station in Germany successfully completed end-to-end data flow assessments for audio and video transmission. Feeder stations for the first Indian Data Relay Satellite System, IDRSS-1, have been set up domestically at the spaceport in Sriharikota and the ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore. An important step toward mission readiness has been reached with the completion of network configuration, testing, and evaluation of these facilities.Pakistan and India
ISRO also used the GSAT satellite to demonstrate data, audio, and video transmission and reception. The Indian Naval Station and SHAR at Sriharikota, as well as the Gaganyaan Mission Control Center in Bangalore and the Gaganyaan
SHAR Control Facility. After successful testing, these cables have also been expanded to connect to the Crew Module Recovery Center in Delhi.
Another significant development is that ISRO and the Swedish Space Corporation have agreed to supply ground station support for the first unmanned Gaganyaan mission.
To further enhance international cooperation and coverage, a deed of license has been executed to establish a ground station terminal at Australia’s Cocos (Keeling) Islands.
In order to investigate the use of AWS ground stations for telemetry, tracking, and command (TTC) operations for Gaganyaan, ISRO conducted a proof-of-concept experiment in 2022, which laid the foundation for these developments.
At that time, ISRO used the SARAL satellite to test one of the AWS ground stations. Although no final decision had been made, then-chairman S Somanath had indicated that the tests were intended to assess if AWS infrastructure could support Gaganyaan operations.

Unlike traditional satellite missions, which depend on fewer base stations, human spaceflight missions require nearly constant surveillance and communication coverage throughout the spacecraft’s orbit.
Former ISRO chairman K Sivan had previously stated that the organization was collaborating with about 40 ground stations throughout the globe to facilitate astronaut tracking, with relay satellites filling in blind spots over isolated areas and oceanIn order to increase mission visibility coverage, plans had already been finalized to move the IDRSS-2 relay satellite after launch.
International agreements were sought, including as assistance for TTC operations from the Cocos Islands during the ascent phase from the Australian Space Agency.
