The Indian Space Research Organisation (ISRO) has indigenously developed Telemetry & Telecommand Processor (TTCP) and its productionisation will be initiated with the help of Indian industry.
The processor development was undertaken up by ISRO as part of ‘Make in India’ campaign to replace the expensive imported equipment necessary for uplinking and downlinking to satellites.
- TTCP has been developed by Bengaluru based of ISRO Satellite Centre (ISAC). Besides, Spacecraft Checkout Group of ISAC is responsible for testing it.
- It will be used by ISRO in Integrated Spacecraft Testing of Low Earth Orbit, Geostationary Orbit and Interplanetary Spacecraft.
- It is configurable to meet uplink and downlink requirements of both CCSDS (Consultative Committee for Space Data Systems) and ISRO standards and multiple clients to remotely access for data and monitoring.
- The system was developed on Field Programmable Gate Array (FPGA) platform. The softcore processor on board the FPGA allows programming all features of TCCP remotely.
- It is being tested on the ground using the same communication protocols that will be used in space. During test, ground systems will communicate to spacecraft via the same uplink and downlink signals, as in space.
- This indigenously developed Processor has been successfully deployed for the first time in checkout of GSAT-19, which is scheduled to be launched shortly onboard of GSLV-Mk III-D1.
