An object orientation and position patch is attached to an object to be observed comprising a planar substantially coplanar and non-collinear reflective locations positioned upon the patch and a reflector having the reflective properties of the surface of a regular curved surface intersecting the planar surface. The computer has a task stored in main memory for detecting and quantifying a change in orientation and position of the object from the location of the image of the orientation and position patch.Other References
