ABSTRACT:
Locating and displaying the relative positions of two objects in a three-dimensional space where one object is a three-dimensional object and the second object has at least three collinear points, at least two of which are sensible by a detector. The detector supplies signals providing azimuth and altitude information related to the two sensible points of the second object for locating the position of at least the third point of the second object relative to the first object which may be positioned inside or outside the boundaries of the first object. The first object may have fixed thereto at least three points sensible by the detector for establishing the position and attitude of the first object within the three-dimensional space.
