FIELD: astronautics.
SUBSTANCE: invention relates to space engineering, particularly, to ground-based testing of space systems. Test method of spacecraft temperature control system includes the following actions. Filling of system paths with liquid heat carrier. Undocking of compensation device. Connection of fluid circuit with fluid circuit of service systems module with standard volume compensator. Heat carrier dose is drained from the volume compensator fluid cavity. At that, from the liquid cavity of the compensating device during draining, the heat carrier dose is measured, which is determined as per the specified ratio taking into account the volume of the compensation device and the maximum volume expansion of the heat carrier in the fluid circuits.
EFFECT: enabling higher reliability.
