In response to the requirements for the development of mass production remote sensing satellites, an optimization strategy for the thermal control system was explored and applied to the development process of a certain batch of Jilin-1 satellites. Compared to the development process of single satellites, which focuses on target feasibility verification, the focus of mass production satellite development is on lower cost and more efficient production. The article follows the idea of integrating structure and thermal control, and conducts thermal control design with low external heat flux sensitivity, low temperature control power consumption, and low material cost; Relying on pulsating AIT production lines and automated production equipment, the thermal control implementation process is refined, thus shortening the preparation time, flexibly arranging personnel workstations, and significantly improving satellite production efficiency; Based on the thermal control design characteristics and experimental requirements of mass-produced satellites, an external heat flow simulation method based on equivalent heat sink is adopted to reduce the complexity of vacuum thermal testing. Currently, 54 satellites of this model have been produced and launched, and the satellites are good in orbit. This thermal control batch production development concept can provide an effective reference for the development of other batch production satellites.
