Abstract
Abstract A fiber optical transmission system for guiding and controlling a missile.he fiber optic link can provide for up and down link transmission that can provide target and reference position information not available to present wire guided missile systems. Fiber optics have an almost unlimited information transfer rate and does not have the electrical interference problems of the wire systems.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
139 words
A fiber optic transmission system for guiding and controlling a missile in flight and to establish the missile position with respect to a target, said system comprising: target sensor means disposed in said missile for establishing the target angular direction in relation to said missile; fiber optic means carried by said missile for transmitting said target information from said missile, said fiber optic means including a fiber optic transmitter, a fiber optic switch, a fiber optic connection between said missile and said guidance and control unit, and a bobbin having said fiber optic conductor wound thereon; a guidance and control unit remote from said missile for receiving said target information and developing missile control information; and, means carried by said missile for receiving said control information and driving control vanes to position the missile along the proper flight path.
