In order to solve the problem of spacecraft collision caused by space debris, the collision model is analyzed and compared. This paper mainly introduces three kinds of spacecraft collision breakup models which are representative at home and abroad, including Battelle collision breakup model, NASA standard collision breakup model and CARDC-SBM of China Aerodynamics Research and Development Center. Finally, taking P-78 satellite as example, calculate spacecraft collision breakup model by Matlab and analyze the similarities and differences. The results show that the models have their own advantages and disadvantages in terms of the size of the fragments, area-to-mass distributions and delta velocity distributions. It provides theoretical foundation for the further study.
