Thermal Systems

Heat flux sensors, infrared radiometers, and thermocouples play vital roles in monitoring and managing thermal aspects of satellite systems, including thermal control, temperature sensing, and performance optimization. They contribute to the overall reliability and functionality of the satellite in various operational scenarios. Here’s a breakdown of where they might be utilized:

• Heat Shield: Heat flux sensors are crucial for monitoring the heat flux experienced by the satellite’s heat shield during re-entry into the Earth’s atmosphere
• Infrared Imaging Instruments: Infrared radiometers are commonly used in satellite payloads for Earth observation missions
• Remote Sensing Instruments: Certain scientific instruments onboard satellites may use infrared radiometers to study the thermal properties of celestial bodies, such as planets, moons, or asteroids
• Heat Pipes and Radiators: Heat flux sensors and thermocouples are employed in thermal control systems to monitor heat transfer rates and temperatures within heat pipes and radiators
• Insulation and Blankets: Thermocouples are often embedded within insulation materials or thermal blankets to monitor temperatures at specific locations on the satellite’s surface
• Solar Panels: Thermocouples may be integrated into solar panels to monitor temperatures and assess the performance of photovoltaic cells
• Power Distribution Systems: Thermocouples are also used to monitor temperatures in electrical components, such as batteries, power converters, and busbars
