Testing of Advanced Features of High Throughput Satellites

High Throughput Satellites (HTS) are built in ISRO with new technological elements and advanced features. These advanced features are implemented with intelligence of auto system reconfiguration and this reduces manual intervention in spacecraft operations from ground stations. Checkout team has major contribution in realising the spacecraft in terms of testing. Checkout team participate right from design review of subsystem till launch. Responsibility of Checkout includes study of spacecraft configuration, preparation of test plan and procedures, execution of test procedures during various test phases and generation of Anomaly Report if any deviation is observed in spacecraft performance. This paper briefs on the advanced features available in HTS, contribution of Checkout Team in generation of test plan and procedure for these features and execution of test during various IST (Integrated Satellite Test) phases on ground.
