| Definition | A pulsed Overhauser magnetometer. It can be platform-integrated (e.g. AUVs and gliders) or towed. It measures the ambient magnetic field using a branch of nuclear Magnetic Resonance technology applied specifically to hydrogen nuclei. It consists of an omnidirectional sensor. Up to three independent gradient directions can be measured (vertical, horizontal (across-track) and longitudinal (along-track)). Configurations available allow it to be used as a gradiometer that measures magnetic gradient in one dimension (vertical, horizontal (across-track) and longitudinal (along-track)) by taking the difference between two independent magnetic sensors Optional pressure or altimeter sensors may be integrated. Absolute accuracy: 0.1 nT. | ||
