The main objective of TCS team in PW-Sat2 project is to perform thermal analyses in order to verify configuration of the satellite, proposed by mechanical team, and to find more optimal solution which will allow to obtain proper thermal balance for electronic and optical subsystems requirements. Due to harsh space environment, temperature limits and safety margins were introduced in order to survive in a hard to predict space conditions. Another objective of TCS is to design the heat management system, in a passive or active manner, which will allow to counteract extreme temperatures.
Currently, the team has conducted thermal test of the Structural Thermal Model (STM) by simulating conditions close to the orbit. To achieve it, a deep space simulator was used (by courtesy of Spacive company), which allowed to achieve -180°C environment, and Kapton heaters to imitate heat dissipation across electronic components and influence of solar flux across the structure walls.
