Abstract

A method and apparatus for a rugged three-axis inclinometer for determining an object's orientation with respect to a gravitational field. Components of the apparatus include but not limited to a magnet, a non-magnetic casing, a ferrofluid, one or more non-magnetic gravitational field aligning materials attached to the magnet and a plurality of angle sensors attached to the non-magnetic casing. In this regard, when the apparatus is rotated, the gravitational field aligning materials maintain a constant orientation of the magnet and the angle sensors experience different magnetic field strengths as they rotate around the magnet. The position of the apparatus, with respect to the gravitational field can then be calculated based on the angle sensor outputs.
