| description | <p>Absolute geomagnetic measurement is very important at geomagnetic
observatories. It plays a decisive role in data quality control and
instrument calibration. As absolute geomagnetic measurements from modern
fluxgate theodolite instruments have high precision, usually within
1 arcsec, the measurement results are susceptible to external factors. The
operator difference is one of these factors and has become an important
consideration that can not be ignored with respect to measurement results.
Therefore, an experiment was designed in order to estimate the operator
difference. Six fluxgate theodolites were used and six observers who were
proficient in absolute measurements were invited to participate. The
observers took turns making absolute geomagnetic measurements, and the
operator difference between the observers for each instrument was computed by
comparing baseline values using statistical methods.</p> |
