Abstract : A method and system are provided to determine the relative orientation of two physical systems (i.e., assemblages of equipment which share a common, locally defined coordinate system). Two distinct beam vectors (i.e. fixed directions in three dimensional space) are simultaneously resolved by each physical system into their apparent vector components. This set of four apparent vectors is sufficient to uniquely and accurately define the transformation matrix relating the local coordinate system of the two physical systems and thus their relative orientation.
