Lessons Learned from the METOP Thermal Analysis and Testing 2003-01-2461

Metop (METeorological OPerational satellite) is a series of three satellites designed to monitor the climate and improve weather forecasting. This paper describes the thermal analysis, thermal testing performed, and relevant lessons learned. For the thermal analysis campaigns it focuses on:

exchange and correlation of reduced thermal mathematical models established in various software formats
sizes and content of the models, in particular automatic generation of reduced models from the detailed models
uncertainties
definitions of thermal interfaces

The lessons learned from the thermal testing campaigns apply to:

selection of test environment, using solar simulation and/or infra-red techniques
selection of test cases based on thermal design driving parameters and/or test chamber capabilities
adequate instrumentation (i.e. thermocouples, test heaters) for all critical components
(un)expected events e.g. EGSE crash, last minute revision of temperature limits, and introduction of special test devices
