Abstract: Aiming at the high-efficiency orbit calculation problem of spacecraft, the research about integral correction methods is reviewed. First, a variety of integral correction methods based on different principles are systematically introduced within a unified notation framework, and a classification comparison is conducted. Then, focusing on the large-step and parallel computing ad-vantages of these methods, the research progress in their parameter optimization and parallel acceleration is summarized. Then, the unique superiority of integral correction methods is elaborated by typical applications such as spacecraft orbit design, high-precision orbit propagation, and spacecraft guidance. Finally, combining the methods’ characteristics and the orbit calculation requirements, the development trends and directions worth studying are analyzed and proposed.

Key words: high-efficiency orbit calculation, orbit propagation, integral correction, parameter optimization, parallel computation
