Autor(en): K. Zajac, J. Richter, T. Schmidt, S. Müller, A. Bergander, K. Seifart
Zusammenfassung: The SWIR Switch Mirror (SSM) Assembly is one of three mechanisms which are developed by HTS for the EnMAP space segment in subcontract to OHB System AG Munich. EnMAP is the Environmental Mapping and Analysis Program of the German Space Agency DLR. The SSM is integrated into the Instrument Optical Unit (IOU) in front of SWIR detectors and allows switching between nominal and redundant position. This paper summarizes the main functions and design features of the Hardware and focuses on qualification testing which has finished successfully in 2014. In addition to standard test campaign required for qualification model (QM) also a shock emission measurement of the release mechanism activation was conducted. Test conduction and results will be presented with focus on deviations from the expected behavior, mitigation measures and on lessons learned.
