<p>A method of obtaining a set of measurements for making a position determination. Laser ranging measurements are made from at least two spaced apart stations with respect to a common distant moving object. The ranging measurements utilise respective signals transmitted from the stations so as to impact the moving object at substantially the same time. By making ranging measurements for a plurality of positions of the moving object the position determination can be made by triangulation techniques.</p> |
