Thermal-vacuum Qualification Test For Space Instrument

摘要

The paper presents preparation, proceeding and results of Thermal-Vacuum test of test the SIR-2~1 instrument for ISRO moon mission Chandrayaan-1. The TV test is the most test for space electronics, during temperature cycle thermal transfer and all electronic are checked. Temperature level, gradient and time of test is related to the target of mission and launch area. For optical measurement, to verify operability of instrument during part of test electroluminescence diodes, mounted in front of spectrometer, were used. After passing all tests instrument was delivered to India and mounted on panel of Chandrayaan-1 satellite. The TV test was performed at the Max-Planck Institute for Solar System Research (MPS) in Katlenburg-Lindau.
