Characterising the Thermal Performance of the European Comet Chaser ROSETTA 2003-01-2464

This paper describes the processes and evolution of the design and verification of the thermal control subsystem of the Rosetta spacecraft. In particular, it describes the testing, both at component-level and spacecraft-level, that was necessary and the subsequent correlation activities that were required to understand the thermal behaviour of the spacecraft and thus develop a thermal model that portrayed this correctly.
