Research on In-Orbit Experiment Scheme of Resistance Standard in Space

This study focuses on the space electrical metrology standards, aiming to explore the variations of electrical standard instruments in the in-orbit environment, establish a space metrology standard system and relevant management methods to ensure measurement reliability for space missions. The paper selects a resistance standard as a representative electrical metrology instrument and explores its in-orbit experimental verification method. It proposes a method for in-orbit comparison measurement of standard resistors, analyzes the circuit errors in the comparison measurement, and presents error correction solutions. The study achieves a compact, lightweight, and highly reliable in-orbit test device, laying the foundation for scientific research in the field of space metrology.
