摘要

From June 2021 to May 2024, three types of Beijing-3 series satellites have been launched successfully. The main payloads of these satellites are three types high-resolution cameras, which have excellent imaging quality. The camera thermal control systems operate stably, effectively ensuring high quality imaging of the cameras. The series of satellite payloads includes three different high-resolution cameras, which have both common requirements for high stability temperature control and different personalized needs for thermal control systems. Regarding the above requirement, this article introduces the thermal control design of camera optomechanical structure, internal heat source dissipation design, thermal analysis, thermal testing, core thermal control products. Analyzed the temperature data in orbit and evaluated thermal control system. On this basis, combined with practical needs, the applicant prospects of thermal control design methods in the field of commercial remote sensing were analyzed. A method for developing a thermal control system suitable for fast, low-cost, and mass production has been proposed.
