ABSTRACT:
A self-aligning global positioning system (GPS) antenna aligns with the earth's surface so as to maintain the integrity of the GPS tracking signal received by a GPS receiver. The antenna element may be maintained within a sealed container which floats inside a spherical reservoir filled with liquid. As a result, the GPS antenna moves along the inside surface of the spherical reservoir in a buoyant arrangement which self-levels the active element of the antenna with the earth's surface.
