Abstract: Space metrology is a technical and management activity that ensures the uniformity, accuracy, and reliability of measurement units in outer space. Focusing on space metrology, this study selected standard resistors and voltage references as research subjects, exploring a ground test hardware platform for space application electrical standards. A ground verification test platform was designed, and through measurement uncertainty analysis, it was determined that the measurement uncertainty could reach the 10^-5 level, laying a foundation for addressing spatial metrology requirements. However, this system has only been verified for a certain range of physical resistors and specific voltage values. Further research is required to develop ground verification systems for other electrical standards.
