Short summary
We present a novel method for calibrating magnetic observatories. We show how magnetometer baselines can highlight a possible calibration error. We also provide a method based on high-frequency automatic absolute measurements. This method determines a transformation matrix for correcting raw data suffering from scale factor and orientation errors. We finally present a practical case where covered data have been successfully compared to those coming from a reference magnetometer.
