Short summary
This study evaluates the data quality and long-term robustness of reference fluxgate theodolites in Geomagnetic Network of China (GNC). Results show high stability in reference instruments and no drift. Operator dependent errors were identified as the primary contributor in observer data. The study highlights the critical role of comparisons. Future efforts should integrate sensors and automation technologies to minimize human errors, thereby providing a higher quality data for studies.
