ABSTRACT:
The attitude of a body 12 is determined, or refined, by illuminating it with a direct beam and one or more indirect beams which are reflected from a scattering surface SS, all of the beams being radiated from the same or adjacent sources. The directions of arrival of the beams are determined to allow the attitude to be determined or refined.
