    From the perspective of control, this paper comprehensively examines the cutting-edge technology and advancements in the precision and agile control systems for high-resolution optical remote sensing satellites, characterized by their ultra-stability, ultra-accuracy, and ultra-agility, to meet the demands of multifunctional and high-quality imaging. It explores the link between satellite imaging capabilities and the performance of attitude control systems, highlighting the critical role of precision and agile control technologies in enhancing optical remote sensing satellite imaging through three dimensions: the capability for multifunctional imaging through attitude maneuvering, the impact of attitude determination accuracy on imaging quality, and the influence of attitude control precision on imaging quality. Building on this foundation, and considering the structure and principles of optical remote sensing satellites' attitude control systems, the paper delves into the primary factors that affect attitude control precision and maneuverability. Subsequently, it thoroughly reviews and summarizes three pivotal technical areas: high-precision attitude determination, precision attitude control, and agile attitude control. Concluding with an outlook on the current technological advancements, the paper forecasts future trends in precision and agile control technologies, centered around the concept of integrated imaging control design, offering a theoretical framework and practical guidance for achieving multifunctional and high-quality imaging control in high-resolution optical remote sensing satellites.
