One example system for determining the orientation of a rotating platform comprises a rotating platform, a first magnetic field sensor configured to sense a magnetic field pointing in a first direction, a second magnetic field sensor configured to sense a magnetic field pointing in a second direction, wherein the second direction is different than the first direction (e.g., opposite the first direction), and at least one magnet producing a local magnetic field. The first magnetic field sensor, the second magnetic field sensor, and the at least one magnet are positioned relative to the rotating platform such that rotation of the rotating platform causes a change in the orientation of the local magnetic field relative to the first magnetic field sensor and the second magnetic field sensor.
