SpaceQuest - Model MAG-3 - Three Axis Satellite Magnetometer - Brochure

The AAC SpaceQuest MAG-3 is a 3-axis satellite fluxgate magnetometer enables reliable and accurate spacecraft attitude measurements. This space-qualified component and its predecessors have flown on numerous space missions from Georgia Tech PROX-1, Bigelow Aerospace Genesis-1 to Naval Research Laboratory missions and is particularly well suited to the radiation environments of high LEO orbits. The low noise magnetometer consists of three magnetic sensors, X, Y and Z, operating independently and simultaneously. The unit consists of a “sense” (secondary) coil surrounding an inner “drive” (primary) coil that is wound around permeable core material. The phase detector identifies key harmonics, and these signals are integrated and processed to produce a highly sensitive magnetic field measurements.
