FIELD: astronautics.
SUBSTANCE: invention relates to the space equipment, and is intended for the spacecraft (SC) and its individual objects temperature regime maintenance. SC thermal control device includes connected via the internal highway: microprocessor, RAM with the digital information output ports, ROM for the temperature settings setting for each electric heater, in which the temperature settings software and device operation modes are flashed, discrete data receiving port, connected to the thermal sensors measuring amplifiers, analog switch, analog-digital converter, digital comparator, information interfacing module. Additionally, into the device the in series connected to the main electric heaters electric heaters, electronic switches, additional shunting electric heaters and controlled from the RAM digital output port, residual capacity sensor connected to the battery and to the onboard computer local controller are introduced.
EFFECT: technical result of the invention consists in increase in the SC lifetime while maintaining the operation efficiency in the orbit all parts, including those shaded.
