The laboratory model of thermal control system is designed for ex- perimental investigations in the vacuum chamber. Experimental investigations of laboratory model of thermal regime under conditions of simulating space enviroment (low space temperature, direct and reflected from the Earth solar flux, Earth heat flux) is carried out. High temperature stability and low power consumption of the system is shown.температуратепловой потокдистанционное зондирование Земликосмический аппаратсистема обеспечения теплового режиматеплозащитаоптико-электронный телескопический комплексразрешение
