Dynamic balance of spaceborne radiometer and research on related on-orbit technology

The spaceborne radiometer, as one of the payloads of on-orbit Earth observation and detection, its dynamic balance characteristics during on-orbit scanning and rotating directly affect the satellite on-orbit detection accuracy and attitude stability. In this paper, the recent research and development trend on the dynamic balance technology of spaceborne radiometer was introduced. Based on the limitations of existing ground-based dynamic balance technology and the requirements of mission development, a preliminary assumption of on-orbit dynamic balance technology was proposed. The corresponding trimming, measurement, and real-time adjustment feedback control technologies for dynamic balance were described. The proposed research may provide reference for the design and control methods of dynamic balance for similar rotary spaceborne radiometers in the future.
