摘要：

This paper brings out the Spacecraft Integration and testing aspects. In case of special environmental requirements which can not be obtained in cleanroom, the test methodology differs and special needs for testing are met in special chamber. In case of INSAT3DS spacecraft, the payload detectors require cryo temperature to be powered on. Hence the spacecraft Integrated level tests for payload detectors are to be carried out inside Thermovacuum chamber with specially designed cryo cooler to attain temperature for payload detectors. The Paylaod data was verified and to meet the specified range of standard deviation, it required the corrective measures of signal lines segregation, stringent control of ground impedances and filtering using ferrite beads. This posed the challenge on Spacecraft AIT to safely handle the spacecraft and electrical interfaces as the activities to be performed on completely ready spacecraft.
