Description

technical field [0001] The invention relates to the technical field of on-board electronic equipment, in particular to a closed-loop test system and a test method for an autonomous temperature control system of a spacecraft. Background technique [0002] At present, two temperature control methods are commonly used on spacecraft, namely active temperature control and passive temperature control. The most classic and most commonly used design method is passive temperature control as the main and active temperature control as a supplement. Thermal control coating is widely used in passive temperature control, while active temperature control generally uses heating plates and fluid circuits. The spacecraft autonomous temperature control system realizes the temperature measurement and control of each cabin section of the spacecraft, and ensures that the structural components and instruments of the spacecraft are in a suitable temperature range in the space environment so that th...
