The invention discloses a precise thermal control device for a high-stability truss rod of a space camera and belongs to the technical field of space optics. The precise thermal control device comprises a radiation shield wrapping the outer side of the truss rod and controlling the temperature of the truss rod in a thermal radiation mode, at least four flexible heat insulation supports fixed to the inner surface of the radiation shield and used for supporting and fixing between the radiation shield and the truss rod, at least one heater wrapping the outer side of the radiation shield, one temperature sensor installed on the outer surface of the radiation shield, and at least one multi-layer heat insulation assembly wrapping the outer sides of the heaters and preventing radiation heat from being lost to the outside environment, wherein the heaters and the temperature sensor form a closed loop temperature control loop and are used for temperature control of the radiation shield. The precise thermal control devi
