<p>The instant invention is a method and apparatus (100) for the measurement, with low uncertainty, of the six degrees of freedom of a first structure (116) relative to a second structure (112). The apparatus (100) is comprised of compact, rigid, thermally stable structures (116, 112). The invention uses linear displacement transducers (110, 108, 114, 106) which have no active pointing to maintain a desired orientation of the linear displacement transducers (106, 102, 104) with other parts of the measurement system.</p> |
