PROBLEM TO BE SOLVED: To provide a temperature control system for a spacecraft, allowing reduction of mass of the spacecraft by reducing a total harness length of a harness for temperature sensors and a harness for heaters.SOLUTION: A temperature control system comprises: a master heater controller 2 controlling a temperature of a spacecraft 1; a plurality of slave heater controllers 3-1 to 2; temperature sensors 4-1 to 3 each connected to one of the slave heater controllers, and each mounted in each temperature control point of the spacecraft; and heaters 5-1 to 3 associated with the temperature sensors. A slave heater arithmetic part turns on/off the heater associated with the temperature sensor and transmits an acquired temperature value and instruction signal to the master heater controller, and the master heater controller transmits a prescribed temperature range set in each temperature control point to the slave heater arithmetic part. |
