The study on the efficiency improvement of qualification procedures for low Earth orbit (LEO) satellites analyzed the differences between the European ECSS and the American NASA standards. ECSS allows flexible test tailoring to accommodate project-specific requirements, whereas NASA enforces strict standardized procedures to ensure high reliability. Additionally, ECSS prioritizes cost efficiency, while NASA emphasizes reliability. In terms of application scope, NASA focuses on private-sector collaborations, whereas ECSS is centered on cooperative projects within Europe. Based on this comparative analysis, this study proposes a qualification framework for Korean LEO satellites, categorizing 18 qualification test items into mandatory and optional groups. This approach is expected to enhance the reliability, performance, and stability of satellite systems. Therefore, the proposed Korean qualification test sequence should be implemented and incorporated into national defense standards. This will strengthen the systematic structure of the qualification process while maximizing efficiency in terms of testing time and cost.
