1. A method of determining the position and attitude of a first body, with respect to a second body, comprising:
- (a) establishing three reference points which are not colinear on the first body;
(b) independently establishing three reference points which are not colinear on the second body;
(c) measuring at least six geometric parameters describing the relationship between reference points on said first body and reference points on the second body; and
(d) computing from said geometric parameters the position and attitude of said first body with respect to said second body.

Abstract
A method of determining the position and attitude of a first body, e.g. a body movable in six degrees of freedom, with respect to a second body comprising establishing three or more reference points which are not colinear on the first body, establishing three or more reference points which are not colinear on the second body and measuring at least six of the distances or angles between the reference points on the two bodies to determine the relative position and attitude of the two bodies.

16. Apparatus for determining the position and attitude of a first body, with respect to a second body comprising:
-
(a) means independently establishing three reference points which are not colinear on the first body; (b) means establishing three reference points which are not colinear on the second body; (c) means for measuring at least six geometric parameters describing the relationship between reference points on said first body and reference points on said second body; (d) means for computing from said parameters the position of each of the three reference points on the first body with respect to the second body; and (e) means for computing from said positions of said three reference points the position and attitude of said first body. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
