ISRO indigenously develops TTCPISRO 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.
