Thermal mathematical model correlation of an earth observation satellite

This paper discusses and outlines correlation of thermal mathematical model of qualification model of Gokturk-2 satellite, which is an Earth Observation satellite with electro-optical payload, with the thermal balance test results. The thermal balance test environment, test instrumentation and test set-up are explained. The orbit altitude for the satellite is 680 km. A companion paper describes the thermal and geometrical mathematical modeling and analysis steps of a similar satellite [1]. Gokturk-2 is a hexagonal shaped satellite with aluminum honeycomb panels. It is covered with MLI and has seven SSM radiators. Thermica v.3.2.20.1 is used as simulator for the test environment and for calculation of radiative couplings [2]. In addition, SINDA/G is used as solver for thermal analysis.
