Abstract:
1. A method for guidance of a moving object towards a target, the method comprising: (a) providing reference signals from three or more polarized RF reference sources to illuminate three or more polarized RF sensors on a surface of the moving object; (b) positioning the three or more polarized RF reference sources to form a reference coordinate system; (c) determining position information designating a position of the target in the reference coordinate system by a forward observer; (d) fixing at least one of the polarized RF reference sources at the forward observer in the reference coordinate system; (e) determining a position and orientation of the moving object in the reference coordinate system on board the moving object based on signals received at the three or more polarized RF sensors from the three or more polarized RF reference sources and based on the positions of the three or more polarized RF reference sources; and (f) guiding the moving object to the target at least based on the determined position and orientation of the moving object and the determined position information of the designated target.
