- ISRO has indigenously developed Telemetry and Telecommand Processor. Its production will commence with the help of the Indian industry.
- Processor’s indigenous development was taken as part of Make in India, replacing expensive imported equipment.
- TTCP will be used in Integrated Spacecraft Testing of Low Earth Orbit, Geostationary Orbit and Interplanetary Spacecraft, ISRO said.
- This system is configurable to meet uplink and downlink requirements of both CCSDS (Consultative Committee for Space Data Systems) and ISRO standards.
- Number of multiple clients can remotely access this system for data and monitoring.
- Spacecraft Checkout Group of ISRO Satellite Centre (ISAC) is responsible for integrated spacecraft testing to ensure the flight worthiness of the spacecraft built at ISAC.
- Pointing out that during the testing, ground systems will communicate to spacecraft via the same uplink and downlink signals.
- This is because as in space, the spacecraft typically use ISRO formats for telemetry and telecommand (downlink and uplink), for which indigenous equipment are being used.
- However, the interplanetary spacecraft use an international standard known as CCSDS, and presently equipment are being imported for telemetry reception and telecommand transmission requirements.
- This indigenously developed Processor was successfully deployed for the first time in checkout of GSAT-19, which is scheduled to be launched shortly.
