Dynamic Attitude Measurement Systems

Leonard Wilk and Todd Hamilton

Abstract:	This paper describes a method for transferring the angular orientation matrix from one system or station to another, and the application of this method to a particular case. Specifidly, this method has been applied to transfer the angular orientation matrix (or attitude reference) near the guidance system of a missile mounted in a canister on a Transporter-Erector-Launcher (TEL), to an inertial/direc- tional reference on the base of the TEL. The mechanization to do this to an accuracy of 0. I milliradian is described in some detail. The method, ‘and device itself, is called AXIS, which is an acronym for “Alignment Transfer by Integrated Strain”. The sensing involves measuring the integrated strain (the total change in length) of line elements on the surface of a long thin rod. The rod is connected to the stations between which the angukar orientation is being transfe.rred. The device can have several implementations, two of which are described. One implementation is photonic; it’s primary attribute being very high sensitivity. The other is resistive wire; it’s primary attribute being relatively inexpensive, The device and the development effort ‘are described in this paper.
