As the complexity of Low-Earth-Orbit (LEO) satellite tasks and their performance requirements increase, higher demands are placed on satellites’ ability to track mission trajectories, including accuracy, speed, capacity resist external disturbances during operation. This paper proposes an anti-disturbance prescribed control scheme for LEO satellites. The establishes a unified framework accommodate high-performance observation, while also incorporating disturbance observer within this counteract unknown disturbances. Unlike existing trajectory tracking methods, proposed allows flexible selection functions adapt diverse demands. By focusing distance between errors function, approach avoids boundary issues faced by traditional control, thus preventing excessive energy consumption satellite. Additionally, framework, is implemented provide real-time compensation ensuring minimal input usage rejection. Our experimental results show that achieves consistent successfully accomplishes tracking, even in presence
