Abstract
A STOP (Structural, Thermal, Optical and Performance) analysis has been conducted on the camera units of the PLATO space mission. The analysis is devoted to the prediction of in-orbit performance metrics that could not be otherwise verified through direct testing. The analysis presented in this paper is restricted to the so-called “static cases” which provide a snapshot of a specified thermal condition. These are intended to evaluate the camera performance over the expected operational temperature range and at zero gravity. We hereby provide a description of the model, the requirements to be tested, the simulation strategy and the performance results.
