Abstract: In one embodiment, an apparatus includes a first magnetometer that measures a magnetic induction and direction of a magnetic field. The first magnetometer has a first coordinate frame that includes a first x axis, a first y axis, and a first z axis. The apparatus includes a second magnetometer that measures the magnetic induction and direction of the magnetic field. The second magnetometer has a second coordinate frame that includes a second x axis, a second y axis, and a second z axis. Each of one or more of the second x axis, the second y axis, or the second z axis is has a predetermined orientation relative to the first x axis, the first y axis, or the first z axis.
