Abstract
A system and method for determining the position of a moveable barrier relative to the fully open position and fully closed position. The invention utilizes in a preferred embodiment a geo-magnetic sensor to determine the extent to which the barrier has traveled from reference position of fully open or fully closed to some intermediate point. A multi-axis sensor provides an output which changes during the barrier's excursion relative to each of the respective axes so that direction or tilt may be readily known in between the closed and open positions. Operation of the gate or barrier may be more efficiently controlled when its precise location between open and closed is known.
