TILT ESTIMATION

An angular measurement device (100) includes a fixable base (106), a suspended element (102) mounted to the fixable base (106), and an angular position sensor (104) operably coupled to the suspended element (102). The suspended element (102) can exhibit oscillatory movement with respect to the fixable base (106). The angular position sensor (104) measures angular displacement of the suspended element (102) from a neutral position of the suspended element (102) with respect to the fixable base (106).
