The Status of the SCIAMACHY Active Thermal Control (ATC)
The Active Thermal Control System (ATC) is providing thermal stability to SCIAMACHY's optical bench module (OBM). Over the past 10 years in-orbit mission lifetime the ATC has proven extremely reliable. Although regular monitoring has revealed some degradation – less than what was predicted before launch – only a single adjustment was necessary so far to keep the OBM temperature within the specified limit. The ATC adjustment occurred in October 2008 in orbit 34643 [RD1 with referencing RD3-RD6].
