| Abstract: | In order to maintain the temperature of a space optical remote sensor in orbit,a thermal control system is designed.The thermal control strategy is primary passive thermal control and assistant active thermal control.A simple simulation of the complicated orbital environment is made,and beta cloth is chosen to prevent AO.Three extreme conditions are confirmed based on its work patterns and heat fluxes.Thermal control design is primary concentrated on the sun-oriented work pattern in low temperature condition.The result of thermal balance test show that the thermal control system meets the requirement of mission,and the thermal design is feasible.Some guidance and reference are gotten from the research jobs for other analogous spacecraft. |
