High-Rel Fluxgate Magnetometer

The Hi-Rel Magnetometer FGM-A-75 is an instrument for measuring three-dimensional magnetic fields. It is based on the fluxgate principle, using three independent ring-core sensor heads for each orthogonal axis. The technical performance data of the FGM-A-75 are based on an ESA qualified unit.
