摘要

The IRS-1C spacecraft has enhanced mission objectives compared to the IRS-1A/1B resulting in a much more complex payload system. The Assembly, Integration and Testing (AIT) of such a state-of-the art spacecraft system posed many challenges in terms of meeting the stringent alignment requirements, accommodating increased number of packages, integrating and testing of very high bit rate payload data handling system along with on-board payload data storage device and development of appropriate hardware and software for testing this payload, the electrical harness design, assembly, integration and testing for the PAN including the Payload Steering Mechanism. This paper gives, in brief, the methodology and philosophy adopted for the AIT operations and the plan for hardware realisation and their qualification. These methods have been successfully used during the Engineering Model AIT activities and the hardware realised will be used for testing the flight spacecraft during all the phases of the AIT activitie to deliver a flight worthy spacecraft.
