Abstract: Magnetometer calibration for shipboard detection of Earth magnetic field anomalies is commonly accomplished by estimating the vessel’s permanent and induced magnetic fields. Crustal anomalies cannot be accurately detected without accounting for the vessel’s magnetic signature. This paper proposes using the magnetometer to produce relative vice full magnetic field measurements to detect anomalies. Magnetometer calibration is performed in a two-step process; the magnetometer is zero referenced and then a maneuver is conducted to obtain sufficient observability of the induced magnetic field. Experimental data collected using a Diamond Nitrogen Vacancy (DNV) vector magnetometer installed aboard a vessel is used to highlight challenges with this approach.
