ISO standard on geomagnetic measurements

The ISO standard for geomagnetic measurements provides consistent guidelines to accurately measure Earth's magnetic field. It ensures that data collected from different locations and times can be compared reliably by defining specific procedures, equipment calibration, and data formats. This standard helps scientists and engineers analyze magnetic phenomena—like changes in Earth's core or magnetic disturbances—by maintaining uniformity and precision in measurements worldwide, facilitating better research, navigation, and satellite operations.
